How my Friend got a Brilliant move Against me

The other day for some reason I was playing my friend RhythmGoya and won (sorry Rhythm.) But anyway, he tells me in the chat below that he got a brilliant in game review. I reply "no", but I didn't actually see the review. So, I eventually go to my Game History and click on that game. And I was shocked:

On the 7th move, Nxf7 he got a Brilliant. Although, I don't really understand why it is one.

Firstly, I see at as more of a material loss than a brilliant move as the Knight captures my f7 pawn I capture back with my Queen and then his Queen trades it, so my King takes back Black's Queen.

I understand I've lost castling rights but I'm still in the lead +2 since he traded the Knight for the pawn.

Well, anyway I don't entirely believe that was a brilliant move, and if I was the Coach, I'd check the Game Review before it's released!
