BLP2E or Subjects notable only for two events is not a policy on Wikipedia.
It is a misconception of some editors that WP:BLP1E can be extended to two (or more) events. Arguments invoking BLP2E as a reason someone is not notable are outside of policy and fallacious. It invokes induction where it doesn't apply. It is similar to saying that a hamburger stored at room temperature will never rot because if it is edible now, it is also edible a microsecond later.
The important part of BLP1E is the number 1. If reliable sources cover the person in the context of more than a single event, then BLP1E does not apply.
