Hip imbalance from hindu squats?

Recently I was told by someone that they avoid doing the above exercise because it encourages hip imbalance. I don't exclusively do hindu squats for leg work, but I do use them from time to time. I don't have any lingering issues, but I'm just wondering: Is what this person said true (Whether this is a personal anecdote or scientific study) in your view? If it is, then how is a regular squat with a free weight or machine any better at not encouraging hip imbalances?
