Yeah, pretty much. The E space does tend to fluctuate, so you can always book the AS segments in coach if it's available and then call to have them switch to E if that opens up. I usually setup an ExpertFlyer alert for it and have probably an ~85% success rate with converting to E at some point before departure.
