So now with another album they could probably actually do a 60 minute set
I don't think it really has to do with only having two albums though. It's that the tours they do usually have five or six bands on them. Then a lot of venues want to tack on a local band (or two) to help sell more tickets. Because of this 45 minute headlining sets are becoming the norm in the US. It would be awesome if they did an hour set, but if there are five bands on this tour I doubt they will have the time.
