That did not matter.
Here is the casebook play that was in affect for the 2014 season:
A.R. 8.12 GOING TO THE GROUND—COMPLETE PASS First-and-10-on B25. A1 throws a pass to A2 who controls the ball and gets one foot down before he is contacted by B1. He goes to the ground as a result of the contact, gets his second foot down, and with the ball in his right arm, he braces himself at the three-yard line with his left hand and simultaneously lunges forward toward the goal line. When he lands in the end zone, the ball comes out. Ruling: Touchdown Team A. Kickoff A35. The pass is complete. When the receiver hits the ground in the end zone, it is the result of lunging forward after bracing himself at the three-yard line and is not part of the process of the catch. Since the ball crossed the goal line, it is a touchdown. If the ball is short of the goal line, it is a catch, and A2 is down by contact.
In 2014 the catch process continues during going to the ground.
They got it wrong and in 2015 Blandino and company claimed to clarify the rule, when in fact they completely changed it to make the rule fit the Dez play. Read the rule from 2012-2014 and then compare it to 2015 and beyond. In 2012-2014 the two feet, control, and act common to the game could be completed at any point prior to contacting the ground, after they blew the Dez play, the act common to the game became upright long enough, which made going to the ground an even bigger part of the game because it required even more subjective decisions by officials. To simplify this from the onset of going to the ground until 2015, if you have control, get two feet down, and then do any act common to playing football, going to the ground ends and you have a catch. From 2015 you have to have control, two feet, and become a runner BEFORE you go to the ground. It became a brand new rule and not a clarification.
