Shelflife

Referees in Ireland
Last week in a Super pacific game , Angus Gardner disallowed a try for a player jumping over the ruck.
So attacking ruck just short of the line, blue player picks the ball up and jumps over the pile of player and touches down for a try .
AG says no try pen against blue you cant jump over the ruck.
But once he takes the ball out, the ruck is over.
Serious law error ? or has there being a clarification issued recently?
