Afaik there is/was no traffic between you/jagex after updating and before you log in.
But i think what ryan means is does jagex watch you when you are in the lobby, not before log in (which i assume you mean before the lobby). Once in the lobby there is traffic between you/jagex.

idk if they still do but they used to log all your clicks on login, which i assume is still active. I bet they do actually log your clicks before your ingame, but whether or not they actually look at those logs is another question.
I don't know why they would even want to look at those logs unless it is about something like inappropriate language. I think it's like the same as player reports, they get them but they don't look at them unless there is some serious reason to look at them.
