Clearly that must be it.
There is currently no case history to base this on you are correct, but look into the laws and pay attention to the details, the edibles recommendation will land you in court without question, because believe it or not they will be knocking on doors soon to count plants, and when it is your door and you have your "edibles" rec for 50 plants, and 45 plants, you will think you are in the clear, but they will take EVERYTHING arrest you, then you can explain it to the judge. Look into what a lawyer costs, look into what happened to Bartowitz, call me an idiot if you want, but you might research this a little more before you start saying things you don't understand. I have a lot of posts in this section if you want to see how much stuff i make up and how much time i really have spent learning the laws the way they are written, not the way most people on here think they are. Good luck to you, but understand what you are getting yourself into, do case studies and understand what really happens when you go to Federal court, and you can't even say the words "medical marijuana" in front of the jury, imagine how well your "edibles rec" will do then.
Take it as you want, believe your doctor has the ability to make the laws not apply to you, its your freedom and money for defending yourself, not mine.
