I discussed technical details of this issue on #pipewire.

This autoswitch is not the default behavior of pulseaudio, but it can be
enabled using the module-switch-on-connect pulseaudio module [1] (the same
module is available for pipewire [2]). Usually, this module is not enabled by
default because it is too aggressive, so it might not be loaded in your case.

If this module if not loaded, then your autoswitch is done via a behavior of
pulseaudio which prioritize previous configured defaults. The same logic has
just been merged in wireplumber and should be available in the next release [3].
