You might want to run commands which only make sense for an
interactive shell. rc files aren't limited to environment variables.

bash reads various files under $HOME at startup. All of these will be
read from the mapset directory, as that is the value of $HOME when the
interactive shell is spawned.

The changes to $HOME are also used to force bash to read the generated
.bashrc file instead of the user's ~/.bashrc, although you can use
--rcfile for that.
