I was under the impression that it will only spread the I/O load if there is enough disk space to do so.  If one drive is getting full, it will only use the other drive.  Auto expire is only a last resort if both drives are getting full.  Here is a quote from the wiki (http://www.mythtv.org/wiki/Storage_Groups):

    The balancing method is based purely on I/O, MythTV does not try to 
balance out disk space unless a filesystem is too low on free disk space in which case it will not be used except as a last resort.
