Not really. It does however help drive home the point that such interjections were unlikely to be used by speakers of Nordic languages in order to begin a tale. (On the other hand in Latin and Celtic traditions, interjections were widely used in story-telling, eg. "Ecce!" and "Féach!" respectively). Old English speakers would have been more inclined to used interjections in a responsive context. For example, to the statement "The boat is taking on water!", one might respond "How?!". But to begin a conversation with an interjection, that just isn't consistent with what we see in any of the speech patterns found in languages which developed from Old Norse.

Do you know the joke about the priest who died, and discovered God meant priests to "celebrate", not "celibate"?

It matters to those who care about this piece of literature. Maybe not as much as a lifetime of coital bliss missed, but who's to say?
