Vinu,
Even if the ground plane carried significant return current, these
currents
are equal and opposite for the pair. Encountering a split plane causes
the
return current for one line simply to do a U-turn, becoming the return
current for the other line. On the other side of the split, the same
thing
happens. The discontinuity is still MUCH less than for a single-ended
line.
