You're corrected in that the served by message doesn't indicate being fttc... It just tells you which cab his phone line goes via.
The speeds indicated on the results though, should loosely tie up with what speeds he's getting.
There's currently several methods of vdsl installation, this will be decided by the ISP or EU. One of these options is self install, where the EU uses traditional nte5a and filters. I could be wrong, but I'm not sure if Bt retail are doing self install yet, I thought they were still mostly sending out either an BToR engineer (or contractor) to fit one of the vdsl faceplates. It could be possible that bt retail have started doing self installs recently though as several other ISPs have been doing so.
