Spell Lists for the new WoW Spells?

Hey all, sorry if this has been asked elsewhere or otherwise made clear, but for the new spells in the World of Warcraft book the ones attached to the Elf lineages (Arcane Pulse and Entropic Embrace specifically) both have class spell lists mentioned in the first line of their descriptions. However, immediately before them under the "Elf Spells" section title it says the elf spells are "available only as part of the Nightborne and Void Elf elven lineages."  Does anyone have the lowdown on how one should treat this contradiction if just going rules as written?

I guess same question with the new spells attached to the WoW classes as well. The Spells for the Death Knight and Demon Hunter both specify they can only be taken by those classes in the spell's description, but the remainder of the spells don't have such restrictions in the spells themselves, but the "Spells" section for each class also says that the spells are added to the spell list for the World of Warcraft classes. Was that just them letting us know the spells existed, or was that saying they shouldn't be used by the regular D&D classes outside of the WoW setting?

Any ideas or opinions are welcome. I understand that the book still hasn't hit the general release date, so not everyone might have had a chance to look at them yet, but I'd appreciate a little help figuring this out.
