If you read "meH'ed noun" as representing a "verb with -meH preceding a noun that it is modifying", then the verb before it could represent the main verb of the sentence.  In other words, I suspect he meant, what you would have preferred to be written as:
adverb - verbbogh 'ej verbbogh noun - verb - verbmeH'ed noun

I misread the initial "adverb" as "verb", and understood that to be the main verb, with the {verb-meH noun} at the end being a misplaced purpose clause. I take responsibility for, and apologize for, that mistake. However, taking that last bit as the kind of construction you explained your intent to be, then I don't see a main verb at all. It's not a sentence. If you intended it to be one, then that's the real error. If it was just meant as a prelude to the remainder of a sentence, any reanalysis I might do would likely fail because of missing context.
