Later in that same page it explains that this would be called back and no touchdown would be awarded to the University of Utah...


From the Rulebook on Unfair Acts:

An obviously unfair act not specifically covered by the rules occurs during
the game. This includes substitutes, coaches or any other persons subject to
the rules, other than a player or official, interfering in any way with the ball
or a player while the ball is in play (A.R. 4-2-1-II, 9-2-3-I and 9-2-3-IV).

PENALTY— Unsportsmanlike conduct. The referee may take any action
they consider equitable, which includes directing that the
down be repeated, including assessing a 15-yard penalty,
awarding a score, or suspending or forfeiting the game [S27].


— Note, if Harlan coming on the field never interferes with a player, the ball, or does not cause an interruption. . . Then it is a dead ball foul and the touchdown counts. But chances are that Harlan's presence at midfield will cause some interference with the ball or a player.
