The FPV wouldn't be giving any "guidance", only "what we're doing right now", I would have thought.
The FPV I am familiar with (not the AB330) gives vertical guidance to the runway provided you place the FPV symbol on the approach end of the runway. Of course, if you start this maneuver high or low, the result is too steep or too shallow of an angle, as the case may be.
VNAV around the corner?
Could be I guess. But, that is ad hoc VNAV capability way beyond anything I know about.
