Hang on OPP kill

What the heck is this, instant app Hang on Killing the Opp?

Are they like trying to do a fast d/c to avoid the loss or some thing?

Obviously a HS close/restart, and I got credit for the win, but did they get credit for the loss too?

edit: funny thing is HS deck tracker didn’t record the game at all. Got bonus stars next match for 3 wins in a row, but tracker only shows two wins. Means deck tracker does not have record of the match I vid cap’d
