The way in which you are going about scheduling 2 backups is not the way we
have done so I can't comment on its accuracy.  However when we want perform
multiple schedules on one machine create a service for each schedule and of
course each schedule has a separate dsm.opt file.  In addition you need to
make sure that you have schedmode polling and not prompted. We have found
that only one session ever gets picked up if using TCP/IP and prompted.
However, if you use polling both schedules get picked up.
