I concede your point, though I still think it’s poor form, given that Okrand gave us a category of words as conjunctions and he gave us a category of words as adverbials and never suggested that any word could be both. He apparently considers {vaj} to be both, simultaneously, and he is humanity’s primary Klingon grammarian.

He's not using it as a conjunction. He's just not being too concerned about distinguishing one sentence from another. This is a common theme in Klingon: independent clauses pushed together when their meanings are tightly bound together. This really shouldn't surprise us: every type of sentence-as-object exhibits this same behavior.

And let's not forget that Klingon grammarians consider 'ej and vaj to be ultimately of the same part of speech, so it's not surprising if the difference between their syntactic functions is a little vague.
