sh(1) needs to know that in order to properly shorten the current
directory path (in prompt) to "~" when you're there.

But none of that seems related to the change above, does it?
All the patch does is: if your current directory is $HOME, but
it's spelled differently, run "cd".  The only thing that does, in turn,
is making sh(1) set the $ENV variable, which it uses to track
the current "logical working directory", eg /home/test. It cannot
obtain that information otherwise, because getcwd(3) in that
directory returns its "physical path", eg /usr/home/test.
