As written, that quote says they will testify that the authorization you possess is real.

It does not say they will offer any testimony regarding your qualifying condition, or the appropriateness of MMJ for your specific situation.

Might be worth talking to them, to make sure they will help in your defense in a more significant manner than just saying "yes that's a real authorization that we issued."
