EHBPC Referee's Need 2 slots to be filled

This probably won't count for the euros as there will be nets, but..

The ball is behind the goal and then hits the wheel of the player defending the goal (from behind the line) and goes back through the goal....

is this counted as a point?

No. When playing un-netted goals, if the ball passes back through the goal, the ball must be touched twice OR come out of the 'D'.
