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.

The 610 was definitely full duplex; see the second bullet at http://www.alinco.com/Products/DR-610T.shtml. I used a 605 extensively on satellite, and a friend has a 610 still.
Just think about how a cross band repeater works, and you'll realize that any radio that does that must by design be capable of full duplex.

To repeat it has to receive while transmitting (that is duplex), but the DR-610T probably does not provide receive audio to the speaker when in cross-band mode. That means it is less useful for satellite work. It gets tricky to avoid audio feedback in that situation. Most repeaters do not have either mics or speakers, but certainly operate duplex. They often have connection for both for testing, however.
