I have only had two races this season in which I needed the second bottle, so the data set is small, but no, I have not ejected the bottle.
However one of the races was Chattanooga Waterfront Olympic, and if the bottle didn't eject on that course I don't think it ever will - that is where I ejected the lid of my Cal Pac, flat kit, nutrition, etc. The bottle stayed firm.
I have used this setup on my previous bikes a lot, and never had an issue. I have found that you really only have issues with ejecting a bottle when it is pointing straight up in the air. The more horizontal the better. I have no trouble getting to the bottle, but again I have lots of practice. I also only use it to swap bottles, so I only remove/replace it once per race. No need to break aero even. In training the rear bottle coms off and I carry my flat & tool kit behind the seat, bottle goes on the frame.

Thanks for providing the great photo. Haven't you ejected the bottle with the zip ties' method ?
Or, isn't it hard to pull out and put back the bottle, during the ride, due to the positioned angle ?
