Lack of communication ?

This is a little old but it's the first time I have seen it. I feel a little sorry for the assistant, surely the referee should be going over to his assistant if not his coms to say last touch was white does that chance your mind.
Thoughts.

Who played it to the offside player? The referee must of communicated it was by Red.
