Very nice pull there!
I'm surprised 200kg didn't go, must have been some savage fatigue accumulation.
Regarding the grip, I think at least in theory a slightly narrower grip is stronger because it's easier to stabilise at the shoulder. Mine is currently moderately wide, because it seems to be a little bit more forgiving on my snaps.
Also, it makes total sense that increase snatching ---> healthier shoulders, at least for someone that has no pre-existing issues. As you say, it demands pretty much perfect shoulder mobility, and the stabilisation stimulus will have swolerfied some important muscles in your back.
