Bouncers trying to get into (unenterable) enemy spawn areas

Bouncers run to the enemy base, and when there are seemingly no other targets in the near vicinity, they will stand at the lower entrance to the enemy spawn area. Isn't this a waste of a bouncer at this point?

Unless I'm mistaken, I thought they go after bots/turrets or the moneyball if there are absolutely no pros to go after?

What map were they doing this on?

I've seen it on a couple. I assume there were pros up in the spawn area, but the bouncer was just in the running motion with his head half inside the no-go zone. He was easily killed by whoever ran by.
