I just analyzed it in slo-mo and believe it checks out. Not going to try to prove—up to anons to look for themselves—but guy behind him is reflected appropriately… I think she's enough ahead of him/closer to camera/simply not positioned where that reflection would capture her, and if she is reflected in that same surface, she would be just off the screen to the right. Note they are coming in from a more brightly lit area as you are seeing their reflections…she's never in that brighter area.
