You've found a secondary source in which the writer did a good job (in fact, a better job than the primary sources of the rule book and official explanations) of putting Item 1 into his own words. He's not changing any meaning here, just making the rule easier to understand. It's important to note that this is an opinion piece. He's giving his opinion, just like we are now. It's also important that this article was published after the 2015 rule changes, which he discusses in the next few paragraphs after the part you quoted.
Rule Change
"However, the NFL changed the rules regarding what a reception is before the 2015 season. The new rule was intended to clarify the old rule, but instead it has just caused more confusion. The new rule states: "In order to complete a...(quotes new rule)...
More Confusion
This has not helped NFL officials much when it comes to determining whether a forward pass results in an official reception or not. There have been many instances since the new rule took effect that have caused controversy."
He's pointing out that in 2015, the NFL changed the rules regarding what a reception is. Again, this is an opinion piece, so it's just a secondary source, and as such it's not proof that the rule actually changed. The two primary sources (the league's rule book and its own spokespeople) are in conflict with each other about the rule change. This writer chose to go by the book, which I'd agree was the right choice, because the book shows that the rule changed. And after all, it
is the only rule book.
Here's
another secondary source putting the rules into his own words, but this one is from
before the 2015 rule change. It's from a Detroit writer reacting to Blandino's tutorial "Explaining the Calvin Johnson Rule."
"The process of the catch is a three-part process -- control, two feet down and then have the ball long enough to perform an act common to the game," Blandino said. "If you can perform all three parts, in that order, you have a catch. If not, and you're going to the ground, you must control the ball before you hit the ground."
According to Blandino, Johnson began his reach for the goal line prior to getting his second foot down, meaning the receiver had to control the ball once he hit the ground.
Had Johnson's second foot touched down before he initiated his reach, the call on the field would have stood.
