This is not such an odd result; it occurs when you simply remove Ornithischia 
from below "Saurischia" up to sisterhood with some clade within Sauropoda. It 
still seems pretty clear to me that ornithischians are derived prosauropods 
of some basal level of organization (just because segnosaurs no longer fill 
the gap doesn't make the gap go away). And then all those "saurischian 
synapomorphies" simply become dinosaurian synapomorphies, some lost (e.g., 
skeletal pneumaticity) in ornithischians.
