There's another clip floating around of him doing the same glitch at the dogs so it's safe to assume that they did it throughout the whole raid ¯\_(ツ)_/¯
Coil glitching is when you switch to the Wardclif Coil, pick up one block of heavy, switch to a different heavy and you'll have max ammo for the one you just equipped.
Cozmo's Official Response: "We have seen the reports that an ammo exploit was used today in the Prestige Raid. This was not the specific exploit we were checking for and we don’t currently have the ability to detect it. Tomorrow we will release the top 3 finishers in the TWAB. You can make your own decision as to who should be celebrated."

The worst thing is that know about that and don't give a -blam!-. But welp, that is "destiny in a nutshell" They protect cheaters, they fix glitches that not all people know most of the time but they don't fix issues that are more important. If they let pass those people doing a "glitch" to complete the raid, then what's the point fixing other glitches? Maybe is because they are using this glitch too, because when something is good for the community and not for them THEN is time to fix it.
