Sentence as object is not defined as "sentence 'e' verb"; it is defined as "sentence1 sentence2" (although there is later mention of the "two-verb (or two-sentence) construction." There are several kinds of SAO, including those using 'e' or net, those using neH in the second sentence, those using verbs of speech, and those using rIntaH.

Personally, I think that the sentence as object is just a subset of the general trend of "sentence squishing" that Klingon regularly engages in. 'uSDaj chop; chev bite his leg off!; Danumlu'; Sa' Damoj promoted to general; bIr; bortaS rur cold as revenge. That is, Klingon doesn't mind shoving short, closely-related sentences together to make a single point. This is why I think Qov's tlhIngan maH; taHjaj remain Klingon is good: one mini-sentence is the setup; the other is the payoff. The sentiment is not complete until the entire utterance is complete.
