That only runs it once.
This is a work around for using ,bashrc when .bash_profile is where this should be done.
I think that advice goes back to a time before modern GUI's. Now many users have never
encountered a terminal, and distros vary widely in the use of ~/.bashrc, ~/.bash_profle, and
~/.profile.
Actually they are fixing the problem of inheriting .bash_profile from the login tothe gui session to running the shell on login mode. So no this is not out of date advice.
On my Fedora 35 box, ~/.bash_profile is:
----------------------------------ser
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
That has been required since the beginning of time.
You always source .bashrc in the profile.
The reason that you do not set important things in the .bashrc is that if you do that you cannot override them from the command line.
For example if you set PATH in .bashrc you cannot then change for any sub shells from the command line.

---------------------------
Some distros have complicated ~/.bashrc or `/.bash_profile files with a section devoted to
interactive sessions. This led to issues where users added settings in the wrong section.
I often ask users to run a failing command in a terminal where they may see messages
that their GUI tools hide, but getting different behaviours between GUI and terminal has
become a problem.
