I'm not too knowledgeable regarding H-1B visas, but the text you quoted was quite clearly aimed at penalizing people (or companies) who attempt to file duplicate H-1B petitions via sister companies in order to better their chances, and that sort of thing. So, as long as your two job offers are legitimately distinct, your companies A and B have little to do with each other (i.e. they are not subsidiaries of the same parent company) and / or the location is different, it sounds like you'd be in the clear. This is just my interpretation of the text, perhaps someone with actual experience on the topic will comment later on.
