That’s fine as a design decision, but what in the standard communicates this design decision?   When I read “8.5.3 SYNC ALL statement” in a draft of the Fortran 2008 standard, I see nothing that would make it clear to a novice that segment ordering does not imply ordering of I/O.  It would be nice to see a note of warning.
