I'm pretty certain they look at all incidents independently. No matter what the on field decision was.

Exactly !!!!! they are running the game. How long before every knock on , dodgy tackle, foot in touch etc etc is checked.
Because even when the ref calls an incident they go back and over rule him, its getting to be a farce.

In fact I will go one further. I will put money on this happening in the near future. A ref will give a try they will look at the incident and whilst the kicker is preparing for the conversion the try will be over ruled.

They can't rule over a forward pass or have things changed ??

The RFL will be that busy looking at Haggerty
1. The knee incident on smith
2. A challenge on Miller that had no impact on the kick but managed to fell Miller
