Certainly you could be right. However, it is a possibility. I have experienced this on a few 8 speeds and can only imagine the 9 speed would be the same (or worse). It tends to not like to stay in gear when dropping that low from the large or middle ring. Obviously, the nice thing about a wide range of gears is the overlap to make accommodations for this issue.

Anyway, just another possibility.
