I'm not inquiring about what value is used, but the behavior of
ENV["HOME"] been added if is absent in the environment.

My question is if this was due memoization optimization or what.

Home directory will resolve with the following logic

It will try the following environment variables:

HOME
HOMEDRIVE + HOMEPATH
USERPROFILE
CSIDL_PROFILE
CSIDL_PERSONAL.

There is no ProfileDir environment variable, but I believe the above
listed options cover what you expected it to do.
