Yes. To add to this: it seems like to avoid sharp changes in experience, like at the point of death/non-death, QI seems to have an effect on the past.

All else being equal, it should be less likely you’ll press a button giving you a 90% chance of dying then a button giving you a 50% chance of dying.

It’s anyway probabilistic and there are lots of factors at play, so hard to disprove.
