Still, it was annoying to see him putting out 1.3 w/kg in front while I was pushing 1.5 w/kg behind him.

The thing about the structured workout people is they can't draft you, but you can draft them. I don't even know if you show up on their screen (I tend to get a little hyperfocused doing workouts), so I think a lot of riders hitch onto them knowing they'll probably put out a lot of watts and tow them around. Then again, the output is likely to suddenly change, too. You wouldn't follow them IRL because their sudden drop in power would have you riding over them.
