Yikes. Thankful that Arraez is back, but we're still dangerously close to the .180 hitting Adrianza getting an AB. Assuming this means Marwin is at 3B. I think a lot of these moves make sense. With Austudillo and Gonzalez on the bench, the team can PH for anyone and shift around positions. I assume they're saving Alcala for the next series and planning for a couple bullpen games between now and WS where they'll utilize roster moves accordingly (though they gotta win first to get there). I can't speak for what these rosters due to chemistry, but I wouldn't roster Avila 'til a longer series, but I doubt any of these moves are of the make-or-break variety.
