Video connecting even after stopping the videobridge2

Jitsi Video continues to work even after stopping videobridge2 and I am able to start a new conference as well. Is this expected?

sudo /etc/init.d/jitsi-videobridge2 stop

I am running the latest jitsi stable version

It works with 3 participants?

Understood the issue, it does not work with 2 participants and as the 2nd participant is trying to join, it stops for everyone.
