Campaigns and GoToWebinar

Hey friends.

I have a quick question about campaigns and how they interact with GoToWebinar through the Eloqua app.

I've integrated two Eloqua campaigns, with different segments and emails, to a single GoToWebinar event. When the 'Are they Registered?' and 'Did they attend' steps are processed within the campaign, will they be respectful of which contacts are relevant and in each campaign ( through it's audience segment at the start), or will it pull back all contacts who 'registered' and all who 'attended' (or not) for the webinar event into both campaigns.

What I'm trying to avoid is contacts being sent emails and follow-up emails from the wrong campaign. And we only want to run 1 GoToWebinar event for both campaigns.
