Sure I've had snakes strike at me. When you own 40 of them, well somebody is going to take a jab at you once in awhile.Is it related to the fact that they all eat in their own home enclosures - likely not since there's no obvious pattern to it to indicate to me that is the reason. Snakes strike occasionally, it's what they do.
Most likely it's not related to feeding or perhaps he's only got his hands in there for feeding so the snake is simply reacting to a habit. There's far too many factors involved in why a snake might strike at you to lay it all at the door of feeding in the environment.
