VERY TRUE. Unless you are 1K or GS, you will most likely be asked for your second choice in case they run out. Even though it is infrequent, I have been on a flight recently where none of the 3 choices were vegetarian (beef-chicken-shrimp or fish something...) I keep the special meal in my profile. Doesn't always work, just like TSA precheck #, but checking this before the flight takes a minute...
