Fortunately AA WN and others do not operate in this fashion.
However, I do not believe it is the norm for all routes - only selected ones where UA doesn't want to give up the freebies.
AA operates this way too. They open up A LOT of seats over time. Most of the time when I can't get a transatlantic flight far out, if I set up Expertflyer flight alerts for award inventory on all possible flights, something will open up I can grabl it.
No program I have experience with does not open up a lot of seats over time. In many programs the most availability is 24 hours in advance. Of course the return can still be an issue.
