If the referee believes he missed something or did not see it properly at the time he can include it for further analysis or report it to the Compliance Officer. This happens mostly when the supervisor has seen something but cannot contact the referee during the game to rectify it, or sometimes when video evidence later shows something that's been missed.
In addition to the above it is also possible the opposition manager speaks to the referee after the game pointing something out that he had issues with. The referee may also include that to see if it warrants further investigation.

Hope this answers your query?
Phucking telt.
