I think the answer to your question, unfortunately, is that there are two separate upgrade lists, because I’ve seen different orders on the app and on the website.

Maybe you aren't flying UA much lately? The cleared list hasn't been in alphabetical order for more than a year.
Random flight I was on yesterday. Note that the first three were cleared ahead of time (in that order) and the last three were cleared at the gate at T-30m. They also appear in the order they were upgraded.
