That's not strange at all. That's how the site is designed, because a selected BA may not actually be the best answer there is for a question. For a while the site was programmed to close questions to new answers after 7 days, but that didn't last long (and ended early 2018).
Users who post after a BA has been selected don't get 2 pts for their answer, but their post does count against the total # of answers they are allowed to post each YA day.

Questions can always be answered, they never close.

Yes, you can still answer old questions even if BA has already been chosen. We've been able to do that for quite a while now.
