CPLZ,
Please understand that I'm not defending the call. I'm not even defending the official. I'm just saying this isn't a "Did the ball break the plane" kind of question that can be settled with a replay.
Consistency in officiating is very hard to achieve. There's a lot of back and forth during the season about how to handle different situations. Different trainers present material slightly differently to different gatherings of officials. The officials accept or reject or understand or fail to understand what they've been told in varying degrees.
I remember one year the state made a big deal about enforcing how many coaches were in the box and keeping them off the field. Some officials flat out said, "My job is to worry about the players in front of me not the coaches behind me." Some said they'd enforce it only if the coaches hindered/distracted the official or the chain gang. Some tried to enforce exactly what was taught and got a lot of flak each week from coaches who didn't like getting flagged for actions that had been permitted the week before. A whole lot more tried to find some middle ground they could safely inhabit. Our strictness was evaluated when senior officials rated our games. It came up at the officials meetings just about every week, and additional discussion seldom contributed to a common understanding. Some officials were directly told they wouldn't get playoff games if they didn't start enforcing the rule.
Celebrations present the same kind of problem. The conferences want to get them under control. There are a lot of officials who have been doing things a long time and have pretty strong ideas about what they will accept. It is very hard to get all of them on the same page. When they aren't, it's not necessarily the fault of any one official. Just suggesting we might want to withhold judgment on a situation whose facts we don't know.
