Interesting situation. But when you say "submit applications", do you mean that you submitted the secondaries and you were complete? And then you withdrew? If that's the case, then yes a few of the members could have read your essay. And you might want to reword it.
On the other hand, if you withdrew prior to submitting the secondary, then chances are slim they read the personal statement. Most schools wait till you are complete to go through your application thoroughly like that. Schools that screen pre-secondary could read essays, but I highly doubt that. Those screens might be more based on number cut-offs.
Again I'm not 100% certain, but if you did withdraw prior to secondaries or being complete, I think you are in good shape. Maybe ask
LizzyM, she would know more.
