This is probably true. I applied in the fall last year, but with a pending January retake that put me on hold at two schools. I was invited to April interviews when my scores came back in February. One was interviewing for very few available spots, and one was explicitly interviewing for the waitlist. I got the interviews (and one acceptance from the first score and a March interview) so it worked out okay for me, but it's not ideal to schedule that way.
If you think you would retake for next year anyway, you might as well do it in January-- you could take the current version, and there's a chance it'll get you another look from schools that might reject you outright otherwise.
