78.8 League Initiated Review -
In the final minute of play in the 3rd period and at any point in Overtime (Regular Season and Playoffs), Hockey Operations will initiate the review of any scenario that would otherwise be subject to a Coach’s Challenge. Hockey Operations will continue to initiate and be responsible for the review of all goals subject to Video Review under Rule 38.4. Where a Coach’s Challenge is available on a scoring play potentially involving “Interference on the Goalkeeper” or “Off-side,” Hockey Operations will, as an initial and threshold matter, determine that the puck entered the net and is a good hockey goal before the play will be subject to further review by means of a Coach’s Challenge (or, in the final minute of play or in Overtime, a review initiated by Hockey Operations). If a team requests a Coach’s Challenge but Video Review under Rule 38.4 renders such Challenge unnecessary, then the Challenge will be deemed not to have been made and the timeout will be preserved.

The rule as it's written is confusing af.....so they look at the play to see if there was any eggregious offside or goalie interference? And if not it's up to the coaches to ask for further review?
