the original {jIghelbe'choHlaHbe'}, (which sparked this thread), was written by Qov as a reply to one of my -kahless knows- numerous questions.
she was trying to show me, how to say something like "I'm not able to stop myself from asking".
back then, being more of a beginner than I'm now, I didn't notice the two {-be'} on the same word. this happened only today, and the confusion commenced.
now, since Qov is an expert I don't think she would have written this word, if the two {-be'} weren't actually allowed.
I wouldn't have said it that way. jIghel 'e' vImevlaHbe' or jIghel 'e' vIbotlaHbe'. But maybe Qov had a reason to say it her way.
There's no known rule against reusing a rover in a word,
but there's no precedent for it and it's very confusing.
Best not to do it.
