Vincent your issue is that you will get all referrers within the visit where that referrer happens. Since the referrer is good for the visit in the segment using hit or visit segmentation. Since you can't use sequential segmentation in data warehouse but for your report you can use then clause for 1 page view which allows you to kill the persistence of conversion variables. [it doesn't matter what's in the segment as long as it doesn't exist. Like pagename does not equal xyzzy and you don't have that page name. It will kill the segment but you will get the referrer.
Hey Tyronne, long time...
I think you are getting caught up in adobe changing pages from a traffic only variable to a hybrid variable that can have conversions applied to it so there is persistence. datawarehouse is showing you all the information for that if still at hp try prop73 which looks like it is pagename also and won't have any persistence issues. because sequential segments don't work in the data warehouse you can't use that trick.
