Fake FG Question

[ITOWN]

I retired from football officiating in 2004 and saw a play last weekend that piqued my curiosity. My son's team was playing in NY(Section V AA) in a championship game and with 4 seconds left attempted a fake FG. The holder caught the snap with his knee on the ground and flipped the ball over his shoulder to the kicker who rolled right. The holder then ran to the left and kicker threw back across the field to him for a game winning TD. Is this play legal? Someone asked if for the holder to be eligible to receive the pass his knee needed to be off the ground when he received the snap. It's been six years since I officiated and I honestly don't remember. Here is a link to the play if you want to watch the video. Forward the highlights to the 2:45 mark to skip to the play. Any officials who help out, I appreciate it.
