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?
What it means is that there's two separate types of review, the automatic (puck entered the net legally, crossed the line, not kicked, no high stick) and the Coaches challenge (which is done automatically in the last minute or OT and is just interference/offside). They are done separately in that order.
i.e.
Goal is scored in a scramble in the crease, looks like it might have been kicked, might also be goalie interference.
First step - Announce to the arena that the goal is under review for a kick
Check the review for a kick, decide there was no kick.
Announce to the arena that the puck was not kicked over the line and it entered the net legally, but now you're reviewing for goaltender interference.
Review shows there was in fact interference.
Announce to arena there was interference and therefore no goal.
