It's true that dancers use a visual fix point, and that also works, probably better. I have no idea why. Do you?

Movements having goals is essential for the way our brain coordinates them.

However, turning in the opposite direction also works, and has a basis in the balance mechanism.

It can help but when dancing Salsa I couldn't simply remove dissyness completely from a dance parter by turning her in the other direction. It could help a bit, but not fully.
