Module preview shows the Tier 4/5 version of Immelmann Maneuver which is tighter, and faces you in the direct opposite direction. The Tier 3 version of Immelmann lasts about a half second longer, which faces you more vertically downward, along with an extra bit of yaw rotation. I personally am unsure if this was intentional, but I also get the impression that it wasn't and it was just never looked at BUT, please look into this and adjust accordingly.
