He's a bit off on the probabilities it looks like. For example the Griz do not have any chance of actually winning the #1 spot in conference. Weber holds all of the tiebreakers over both the Griz and UND so they've won the regular season title.
Also in his "Magic Number" thing it shows the Griz do not control their own destiny when it comes to getting 2nd place, which they actually do. If the Griz win the next 2 games since they have the tiebreaker on UND even if UND wins their last 2 the Griz get the #2 spot in the tournament. The fact the Griz split with Weber and UND lost both games to Weber gives the Griz the tiebreaker over UND.
