what do you call the variation of a snatch where you land in a full squat with the bar over head? I would call what he is doing a power snatch.. and yes I'm a crossfitter
That would be called a "snatch" (also full snatch or olympic snatch). This is, indeed, a power snatch. Rip would agree with your assessment of this movement as a power snatch as indicated by the very first sentence of the video whose subject is "the power snatch". You being a crossfitter doesn't bear any semblance to the veracity of your claim that this movement is a power snatch and not a full snatch, but thank you for sharing that information regardless.
The difference between all those olympic movements and the power versions is that the power version ends in a lightly squatted position, and the olympic version in a deep squat.
