That's an interesting question.
The text of the video you posted isn't part of the lore, really....just the posters interp, so I couldn't give you a yes or no answer. I think that she has a Universal viewpoint, that all religions hold to One great truth. There is a story about the Mead, but it doesn't imply that the woman
is the mead or anything. She sort of mashed a few sagas together to create that storyline. The mead is a mead of poetry and divine wisdom that Odin steals from the giant's daughter and gives to the Aesir, but as he's pouring it out, he spills some on all types of creation and that's how poets (human ones) were born. From my understanding at least, and I'm not really into the Advanced studies of the myths yet.
There's some debate on whether or not there is a belief in reincarnation with the Heathens. I have seen some accounts in it in the Eddas, but the general belief seems to be that death is death and there isn't a rebirth back into Midgard. I found myself more interested in the Volva that was awoken, who claimed to be burned three times ( this is lore). It's also never implied in the myths that that is Freya, and I was working on an idea that any volva that dies gains an all-knowing wisdom of things before her time...I don't know quite yet.
The burning is supposed to represent the intitiation process..that particular volva was of gold...so it could all be very Alchemical. Transformation, ritual death, etc etc.
The interesting thing is what poetry means to the Norse. To us it implies flowery sonnets you know, but poems were used in a different way back then. The alliteration, the beat of the stanzas, the rhymes were all memorization tools. The most important messages were put into poem form for easy memorization and recitation. There was a very specific way poems had to be constructed....kind of like a secret code. It's one of the reasons the Eddas survived from generation to generation orally, and also how we know that certain stanzas or lays actually came from the era and not a corruption during a later date.
So knowing that, and knowing that Odin drank the Divine Wisdom that spilled unto the poets, and that poetry is how they passed on their knowledge and wisdom in riddles, it gives a whole new meaning to the stories. And that's why people (including myself) try to interpret them and decipher the meaning. Sometimes it's metaphor, sometimes it's cut and dry. It's always interesting. (To me at least.
)
Ok, I'm done rambling!
