This term applies to 2BR villas only. A dedicated means that there is only one entrance to the villa. A non-dedicated room means that it is a 1BR and a studio put together. There are 2 entrances to a non-dedicated.
Besides not having a second entrance to the villa, in most cases, a dedicated 2 bedroom has 2 queen beds in that second bedroom. The only exception to that is at BCV where some of the dedicated 2 bedrooms have a pull out and 1 queen. So, if you are booking a dedicated 2 bedroom at BCV, and you want the 2 queens, you have to ask for it, and if you get it, it says so on the confirmation sheet that you get.
