WAAS for GNS 430/530?

Does the computed glideslope indication meet obstacle clearance (i.e.
stepdown altitudes and whatnot) even if the approach is flown a couple
of dots low on the glideslope indication? Or does the pilot/autopilot
need to be absolutely sure that the approach is flown smack in the
middle or a couple dots high?

Regarding the "straight line from FAF to VDP passing under a
stepdown",
that's handled by a charting a delay before descending until reaching
a point
from which the stabilized descent *will* meet obstruction-clearance
criteria.
The CNX80/GNS480 follows that charting.
It does not start the descent from the FAF when it's incorrect to do
so.
