Not always.
git config foo.bar old-value
git config unset.variable foo.bar
git config foo.bar new-value
One could expect the new value to be taken into account, but it is not.

I think you missed the "another" in my sentence above. The normal
use-case is to have foo.bar and unset.variable=foo.bar in different
files. In this case, you do not care about the position in file.

If my sysadmin has set foo.bar=boz in /etc/gitconfig, I can use
git config [--global] unset.variable foo.bar
and it does work. Always.
Playing with the order of variables in-file is essentially useless OTOH
except for the include case you mentionned (if I want to unset a
variable in a file, I'll just delete or comment out the variable and I
don't need unset.variable).
Really, I don't see the point in making any complex plans to support the
useless part of the unset.variable feature. The reason it was designed
for already works, and $EDITOR does the job for other cases.
