I believe this is the operative statement.  I haven't tried it in a while (years), but I recall that my Alinco DR-610T mobile rig was not able to receive on 70cm while I was keyed up on 2m for a satellite contact.  I remember this because it's frustrating when you can't hear what's going on.  Haven't tried V/U satellite mobile since (and that was while parked in my driveway).

The DR-610T is definitely capable of Cross-band Repeat, however.
