There is no ruling about the length a ballroom dress should be, and it varies from year to year with fashion. My own dresses are slightly longer than "ballerina" length, as that is the style in which I feel most comfortable. Most ballroom dancers would not wear a dress longer than ankle length because it would be dangerous - when lowering to take a back step, it would be easy to step on the hem of the dress and fall.
Although as choreographers and not ballroom/Latin experts, Craig, Arlene and Bruno would not be able to judge footwork in a longer length dress, a judge of Len's experience can tell whether the footwork is correct by the balance, and as he said, the body position, of the dancer.
In the same way, a teacher who is actually dancing with a student, and therefore unable to see the feet, will still be able to tell if the footwork is right or wrong by the way the student moves.
[I should add, that juvenile dancers - i.e under 12s - are restricted in the length and style of dresses]
