Once at work i had the truck on the lift and both wheel where lock together i had to spin a couple of time one wheel in both direction to release it.
I am not sure what you mean by the wheels were locked together but that sounds more like a locker than a Torsen. Your explaination could also happen with a Torsen due to the gears in it needing force to get them to start working to get the rotation of each wheel to be different.
The Torsen differential is basically a limited slip differential and other than a few properties unique to the Torsen it acts like a LSD. If you have one wheel on ice, a LSD does not guaranty that you will not get one wheel spin. Yes, it transfers torque to the opposite wheel but if the slipping wheel accepts no torque there is no torque to transfer. Lightly applying the parking brake helps in a situation like that.
I have over 80,000 miles on my Torsen, much of it off-road, and it still works as well as it did when I bought it new. One of the advantages of a Torsen is there are no clutches to wear and it remains functional longer. Any mechanism like that can have problems but overall they work well. They are not magic but are not a plie of crap either.
If you want both wheels to spin when one does not have traction, then you need some type of locker.
