Really stupid announcers. If they had actually watched the game, they would know that this offensive line did this several times throughout the game (in the other instances the entire line did it as a group). They do this when they believe that the defense has jumped offsides (crossed the line of scrimmage, or the line where the two teams meet, before the beginning of the play). Since there is often confusion as to whether the offense or defense "jumped" first, oftentimes the wrong side will be called for the penalty. This team has devised a strategy wherein if they believe the defense has jumped offsides, they remain perfectly still to remove all doubt. In this instance, it backfired as the right tackle saw something the rest of the line did not see.

Well, okay, nibiyabi gives it new perspective. But it still makes a hilarious clip

It is hilarious, more-so out of context. Forget your perspective nibiyabi! I want my reality kept pure and without context.

He was either afk or lagged out

I don't understand what the benefit would be to remaining still once it's clear the refs are not going to throw a flag? The backfield can't yell "no flag" or something to let the O-line know?
