SHARES clears NRSA starting in the E+ cabin based on seniority. They absolutely do not clear them into E-.
To be fair, SHARES used to process NRSA from back to front, which means junior employees would get the best seats.
Thankfully this was reprogrammed in mid to late 2012.
I still prefer how legacy UA agents usually clear NRSA - one by one at the podium, and letting you know what seats are open.
