I can't comment on the reserve grade incident - missed it sorry.
The logic behind your first grade keeper was that both parties were airbourne and challenging for the ball. I agree with you that if a similar incident happened bewteen two field players, a foul would have been called and probably a caution given. I think that this was over-looked due to the fact that the situation resulted in a goal. If I were refereeing, I would have cautioned him - a red would not have been warranted though, he did have eyes for the ball.
