I think I you can easily verify by asking. No one can take away your CHL privileges. I believe, what they are saying when you do patrol under their program they do not want you to be armed. The reasoning is that you may think or believe that you are now like a police officer with only 1-hr training. You may draw your firearm to stop a crime and get into hurting an innocent person and PD would be civilly liable.
By law, CHL can use deadly force to stop a crime (e.g. attempted murder or robbery with a deadly weapon) against a third party.

In my town, you need to go through 13-weeks ( 4hr per week) training to get into Police Academy, Once you graduate, you can enroll in Citizen on Patrol, where you do 4hr shift in real police car!. That is cool for me. But, also, no CHL armed citizen is welcomed. If you are caught you get dismissed from the program.

I find it is very risky to be in patrol car and un-armed while reporting a gang bang assault on someone. You could be get caught in the cross fire unarmed.
