So the conclusion is that the logic to see if the names are the same
needs a bit more work than what was posted, I think?

Sorry, but I am not sure what you are asking.

Do I think the assignment to $sanitized_sender can and should be
done just once, not once per file, if the code inspection tells us
that $sender is a constant inside the foreach (@files) loop?

Do I think these two are solving pretty much the same thing and is
better to be done in a single patch?  

I didn't really think them through when I responded, but now after
you made me think, I would say the answers to both of them are yes.
