Where did the p2099 code never come back on?

Last year we took about a 400 mile round trip from Baltimore to Ocean City in our used 2010 Acadia. While there I fueled up and on restarting a P2099 code set.

Why is p2099 only thrown for bank 2?

Especially comparing the two banks. P2099 is for bank 2. Now that doesn’t mean you can’t have a system wide issue like a faulty mass air flow sensor only throwing a code for one bank. Could be that it just passed the monitor for bank 1 and only bank 2 went past the threshold for flagging a code.
