Yes it feels different. Then again, any two reps of overhead press feel different. How different does it feel? Not much. I could understand if you planned on doing three worksets for a muscle and wanted to distribute that across three different exercises to get a slightly larger range of stimulus than you would get from doing all three sets on the same exercise. Not that its going to make a huge difference for the most part, but I can understand. In fact, that's what I do.
But in this video, hide is doing four or more sets on three different nearly identical exercises. What is the point? After the first one, he's already warmed up and blasted -- he would need one, at most two light sets to get the feeling for the new exercise after switching to a work set. It's kind of hard to tell, but it looks like he's just doing straight sets or a typical ramp up for each overhead press variant. That seems totally pointless to me.
