so is this optimal for assistance training?
Also, isn't prehab work that is done to prevent injuries? How would something like this be prehab?
In many cases yes. Sometimes, however, you may want to go heavy with your assistance work. Examples could be seated rows, or weighted dips. It all depends on the exercise.
That said, in the 5/3/1 example you may do 4x10x50% deadlifts after your work deadlift worksets. This would be considered a hypertrophy and/or prehad series.
