Activation Groups 102, the plot thickens....

 >> The shared open (also issued in the DAG) does not percolate.  Same
parameter, same program; different behavior.

Not the same program - it has been recompiled as an ILE program running in a
NAG and therefore behaves according to those rules.

The reason for the difference (my brain is clearer than when I wrote
earlier!) is that an OVR is an OS level thing - in other words it just
affects the lookup process as does a LIBL.  On the other hand a shared open
is a sharing of the ODP.  Since the ODP is _owned_ by an AG (OVR is a
question of visibility not ownership) it cannot be visible to other AGs
(including the DAG).  And thereby hangs a tail.

While we were striving for compatibility - it was compatibility for existing
code - run without changes.  Not your case I'm afraid.
