Super Bowl XII Dallas Cowboys vs. Denver Broncos: Touchdown??

Here is a commercial that is sponsored by Tri-State Toyota Dealers and it's from 1980. It is called "The Winning Moment" and it shows a touchdown pass during Super Bowl XII in 1978. The teams were the Dallas Cowboys vs. the Denver Broncos. The touchdown pass is from Roger Staubach to Butch Johnson.

Would that be called a touchdown today? Hmmm...What do you think??
