Do people around TortoiseGit lurk on this list?  Otherwise this may
not be something we can help you with here.

Yes, this is a real issue, and I do not mind seeing a patch to
improve the situation (there may be different approaches, and one
random approach somebody takes may not necessarily be a good way to
improve the situation though).

 - Perhaps by allowing an option to tell the "pull" at the fourth
   step to record swapped parents in the merge?

 - Perhaps in step #3, stop suggesting to "pull first" and instead
   tell them to "fetch upstream, rebase your work on it and then
   push"?

 - Extending on the second one, wrap a large part of the procedure
   in a single handy wrapper "git update" or something, whose point
   is to "update your work to be mergeable and pushable"?

If we flip the resolution process to "apply/merge your work to the
updated upstream (i.e. the topic of your problem #2 above)", that
"other way round" issue will disappear, no?

Likewise.
