It's not as black and white as that though is it
I see no reason why a bodybuilder wouldn't do strength work and then break down into hypertrophy assistance.
Incline Bench Press: 6RM - A true 6RM or something like 10/8/6/4, hell even 5/3/1
Dumbbell Bench Press: 4x8
Flies: 5x10
Using a template like that you have plenty of chance to increase muscle fibre activation as much as possible, bump up all your assistance lifts with strength work and provide enough volume to build effectively. Which is why many pros use this kind of template (yates, coleman and greene all used a similar method in their videos) and why DC training works so damn well
lol pretty close to my routine at the moment,
5/3/1 with
My assistance
Squat day : Lunges, bent over rows, wide pullups, calf raises (Low weight, High volume)
Bench day : Chest dips, upright rows, barbell curls, abs (low weight, High volume)
Dead day : Dumbell rows, Pulldowns, Good mornings, calf raises (heavy, low volume)
Press day : Incline Dumbell bench, Close bench, Bicep curls, abs. (Heavy, low volume)
But that's a different topic. As a "body-builder" the strength training is more of a short term thing, my focus is always on the hypertrophy part of my training. I will drop the strength training in a month or so I reckon.
