Er, no. It uses the lowest landing gear AGL distance, which these days comes from the new groundcache code. I assure you it's not using the view location for AGL altitude, as evidenced by the fact that the aircraft doesn't fall through the terrain when you switch views. :) As far as the net-fdm issue goes: you may be stuck. The FDM is the piece of code responsible for deciding on terrain interaction under the FlightGear architecture (it has to be, if you think about it -- otherwise no one is in charge of gear force). How does your external FDM make its own decisions about ground interaction? If you can't get the answer there, you may have to write some C++ code to query the ground cache on your own.
