Seems a more likely origin for the described difficulty, IMO, than
the FEOD being discussed.

OK - having y'all for a blank wall is always helpful - will let you
know what's up - because it seems the FEOD should have worked.

Seems to me that "the FEOD should have worked" to ensure the records
from the previously buffered WRITE activity [into the ODP] would have
been made available in the physical dataspace and the maintained access
paths, *if* the F-spec had instead been defined with File-Type=O [i.e.
Output-only].

However given the File-Type=U [i.e. Update-file] and irrespective the
File-Addition=A [i.e. to enable Add records to the DISK file], as was
described in the scenario from the OP, the Force End of Data (FEOD)
should not play any role. That is, the FEOD should have had no effect,
just as was determined from testing. There also should not have been a
message about RPG using buffered I/O as an effective reminder about the
possible need for an FEOD on that file's ODP; i.e. no RNF7086 "RPG
handles blocking for the file. INFDS is updated only when blocks of data
are transferred." in the compiler listing.
