This was all my past problems with the exercise....

Right on the money. I was just saying the same thing to someone else.

But I'm not sure about these instructions from Matt. Is he saying to lower your head or actually push the neck and head forward sort of like a buzzard? It sounds like the latter. I can't say I feel good about that as posturing the neck in this way is really one of the worst things you can do during ANY heavy lifting. It's really a no no and leads to cervical strains/injury as well as shoulder problems. I actually just concentrate on lifting the weight straight up and over my head which means I have to pull my face back out of the way a little but I don't look up at the ceiling or anything.

Lower Cervical Disc Injury
Injuries occurred almost exclusively during exercises where a) the lower cervical spine was in a flexed position (the chin was protracted and forward of the torso and b) a muscular force was produced in response to a resistance, which further flexed the lower cervical spine (C5-C7). This may cause trauma to the ligaments and discs resulting in referred pain to a variety of soft tissue and peripheral locations.
If loading occurs when the neck is in this position, forces are directed along the cervical spine's longitudinal axis, initially causing compressive deformation. When the head is held in neutral position the loading forces dissipate in lateral flexion, flexion or extension. Thus, the cervical spine is able to sustain loading due to the ability of the musculature, intervertebral discs and ligaments to absorb energy. (Taylor)

Most of the time behind the neck presses are talked about or things where the neck muscles are loaded but I wouln't purposely place the neck in a non neutral position when the spine is loaded if I could avoid it. That would inculde military press, squats.

I'll add this to be thorough:

CERVICAL SPINE INJURIES

While not as common as back injuries, neck injuries occur fairly frequently in weight lifters. Cervical spine problems include mechanical sprains and strains, disc injuries, and brachial plexus injuries. Soft tissue injuries may result from protruding the head forward or from unnecessarily tensing the neck while weight training. Some problems result from a muscle imbalance syndrome similar to the "upper crossed syndrome" described by Janda.(46) This problem occurs because of imbalance in training programs that involve an inordinate amount of exercise for the pectorals, the front delts, the lats, and the biceps and very little training of antagonist muscle groups. The result can be overly developed and tight pectoralis major and minor, latissimus dorsi, front deltoids, trapezium, biceps, and stemocleidomastoid muscles, especially if proper attention has not been given to maintaining flexibility in these muscle groups. It is often accompanied by relative weakness of the middle and lower trapezium, rhomboids, the upper thoracic extensors, the deep neck flexors, the rear delts, and the external shoulder rotators (the infraspinatus and the teres minor).(33) It results in the rounded shoulder, forward head posture frequently seen in bodybuilders.

Exercises in which the head is allowed to nod or protrude forward may contribute to cervical spine injury by either promoting the postural defect noted previously, or by predisposing the athlete to cervical disc problems. The tendency to jut the head forward in exercises such as shrugs (Figs 3 and 4), behind the neck presses (Fig 5), behind the neck pulldowns, lateral shoulder raises (Fig 6), triceps extensions, curls, incline leg presses, and abdominal crunches promotes the development of the rounded shoulder, forward head posture. This posture is associated with abnormal mechanical function of the cervical spine. It is characterized by adaptive shortening of the suboccipital muscles, the stemocleidomastoid and the anterior scalene muscles, and excessive tension and weakening of the long cervical extensor muscles, the levator scapulae and the scapular retractor muscles. Trigger points and/or muscle strain may result in any of these muscles. Either upper cervical or cervico-thoracic joint dysfunction may result. Not only do cervical pain syndromes occur, but also temporomandibular joint dysfunction and headache. (47,48)
