Quote from phiggsbroadband:
"A lot of people have been calling this manoeuvre a 'Loop', but from the videos, it seems to start off as a loop, but then has a 180deg roll on the 'up portion', before going into the inverted.
Maybe some aerobatic pilots could give this a name, could it be part of a 'clover-leaf'?"
I'm also struggling to get my head around it, but this post on the Military thread suggests it was a "quarter clover":
