Actually, if the entire routine was JUST multi-joint/full body movements I wouldn't necessarily even bother with the push/pull balance. In snatch an cleans there is ample pull movement to counter the push... especially when you consider that the "push" is virtually nothing if done correctly. However, any time I see the bench press my ears perk up. Even overhead pressing involves enough stabilization that if done by itself it won't cause any harm. The back is still very active in holding a bar overhead. But in the bench... it is such a quirky little lift that I feel like people need to stack up on the pulls to avoid some common pitfalls.
