As far as I know, the judge at FH has no access to information from FDR.
Our judge only had whatever was in the bundle which was supposed to have been agreed by by both parties before the FH.
Regardless, I see how one could get suspicious. Ours asked for time to go away (after 3 day hearing) to think about everything and come back with judgment. It's left me wondering whether they ever consult the other judges (from FDA and FDR) - not that that would be a problem!
