That article relates more to the people doing ridiculous amounts of volume or doing 'kill sets', I think.
I think Dave has a good point. Everyone ends up with a forced rep or a missed rep sooner or later. Preferably later
Look at it this way, doing rippetoes program (for example) you can smash through PRs for quite a while before you end up missing reps. But once you miss a rep it becomes that much harder to keep setting new PRs. Training to failure is not ideal, but look at the progress you make leading up to your first couple missed reps.
