Hi,
It would seem that it changed nothing...

$ alternatives --verbose --auto python

reading /var/lib/alternatives/python



$ ls -glo /usr/bin/python

lrwxrwxrwx 1 13 Jun  3  2015 /usr/bin/python -> python2.7.exe



$ alternatives --display python

python - status is auto.

link currently points to /usr/bin/python3.9

/usr/bin/python3.9 - priority 39

Current `best' version is /usr/bin/python3.9.


Martin
