More than 45 minutes on bench press?

I work out in a small gym, usually 4 or 5 people in a ~2000 sq ft gym. I’ve noticed one guy, who is much stronger than me, has some odd routines.

This morning he worked on bench press for a very long time. I wasn’t keeping track of time, but he was on the bench press while I completed 3 to 4 sets of the following: -Squat -Leg Press -Leg Extension -leg Curl -Bulgarian split squats

When I left, he was still there. I didn’t pay much attention to his exact routine but he was definitely lifting and not just on his phone.

As someone who really wants to work on chest right now, was that a real routine? Do any of you dedicate that much time to one exercise?
