This was a mistake in the original code from D1079. With the current way how direction ot mirror ball works camera should look into negative Y direction. Corrected it in the camera matrix synchronization, so no extra calculations are needed at the render time. That's a bit annoying, but we'd better port it to the release branch, or otherwise we'll end up with files created with wrong camera mapping after 2.75 release.
