How was this route done?

I stumbled on a video posted to Reddit and the OP was asking how this was possible and wondered if red zone threat was the key. Nobody had an answer other than it being a glitch. 
 

Watch Delanie Walker. He makes a second move to the inside on a designed corner route.

did he run a post in the redzone or something? cuz if so, its a glitch rn that if u hot route a post in the red zone with ur player that was rzt, he would do like a double move or a post corner

Tbh I’m not sure to me it looks like a designed corner route. It probably was that glitch you’re talking about. Never seen anything like that and was hoping they just added more double move routes. Thx man
