In current MEMA this already changed (though, not published - I wait
results from Massimo then find what wrongly works in EXT_get() on 8086). If
you wish, I send you current MEMA.

Here part (64k) of upper memory assigned to EMS page frame instead UMB.

This is because page frame substracts 64k from UMB -> some programs
doesn't fit into UMB and placed into low memory. Let count: was free 49.3k
of upper memory, now free 4.2k, this mean that 64k-49.3k+4.2k=18.9k of code
moved from upper memory to low. Now see: was free 619k of low memory, now
600k. All as expected.
