I'm in the same kind of corporate Windows environment and I can
replicate your results.

When %HOMEDRIVE%, %HOMEPATH% and %USERPROFILE% are all defined in
the environment, and %HOME% is not, I don't think I particularly
care whether Vim synthesizes %HOME% from %HOMEDRIVE% and %HOMEPATH%
or from %USERPROFILE%, but I do think it should be consistent. When
Vim is started, it should look at %HOMEDRIVE%, %HOMEPATH%,
%USERPROFILE% and %HOME%, and if %HOME% is not defined, set it
according to some algorithm and leave it alone. It appears that Vim
is instead creating %HOME% differently for different purposes.
That's not good.

For the record, the environment of my cmd.exe includes:

HOMEDRIVE=G:
HOMEPATH=\
USERPROFILE=C:\Users\gary

but no HOME. From the Start menu, Windows runs cmd.exe in my
%USERPROFILE% directory.

I first run gvim like this:

"C:\Program Files (x86)\vim\vim81\gvim.exe" -N -u NONE Documents\tmp3.txt

Vim's title bar says:

tmp3.txt (~\Documents) - GVIM

I enter some text in the file, then

:w
:mksession
:q

Then I run gvim like this:

"C:\Program Files (x86)\vim\vim81\gvim.exe" -N -u NONE -S

Vim's title bar says:

tmp3.txt (G:\Documents) - GVIM

The status line says:

"Documents\tmp3.txt" [New File]

Gary
