First - call MAAC or your ZD directly for teh official word on this.
second, the safety code includes the following.
. I will not fly my model aircraft in the presence of spectators until I become a qualified
flyer, unless assisted by an experienced R/C Pilot.
That said, if the instructor that was assisting you was known and approved by the host club ... that should be fine. If you were visiting a club, they woudl have to know of and approve the 'experienced pilot.'
