I can entirely understand why they didn't make the Volkihar as the book says they are.
It would cause a lot more glitches if they made it so you can phase through the ice and what not.
It would cause A LOT more whining from people about being a Vampire ruining the game's experience due to everyone wanting to kill you no matter if you fed or not (see most people who played Morrowind and ask if they played a Vampire and enjoyed it or not), Bethesda obviously forsaw that so they kept the previous system but improved upon it.
Also..they already broke the Lore even before Skyrim..in Daggerfall the vampires could blend in perfectly.
By the way, Movarth in-game unless confirmed by Bethesda IS NOT the same person as the Movarth in the book.
