ok i got it.
78.6 Video Review - No goal may be awarded (or disallowed) as a result
of video review once the puck has been dropped and play has
resumed following the first stoppage of play after the potential goal.
See Rule 39.
When a team scores an apparent goal that is not seen by the onice
officials and play continues, the play shall be reviewed by the
Video Goal Judge at the next stoppage of play. If the goal is confirmed
by video review, the clock is re-set to the time the goal was scored. If
the goal is not confirmed by video review, no adjustment is required to
the clock time.
Only one goal can be awarded at any stoppage of play. If the
apparent goal was scored by Team A, and is subsequently confirmed
as a goal by the Video Goal Judge, any goal scored by Team B during
the period of time between the apparent goal By Team A and the
stoppage of play (Team B’s goal), the Team B goal would not be
awarded. However, if the apparent goal by Team A is deemed to have
entered the goal, albeit illegally (i.e. distinct kicking motion), the goal
shall be disallowed by the Video Goal Judge and since the play
should have stopped for this disallowed goal, no goal can be awarded
to Team B on the same play. The clock must be re-set to the time of
the disallowed Team A goal and play resumed.
