The only issue is if you own the yourself you won't see the person sharing it's version.
For instance, my friend bought the Bioshock pack on Amazon (Got 1, 2 and Infinite) and I have Bioshock 1, 2, Infinite + Season Pass. He can't see any of my Bioshocks because he has them already even though I have DLC on Infinite.
