If it is similar, but not the same, then I would say it's fine. The questions are meant to be for particular things, not a general area. For example, if were to ask a question about apples (not to be done on this particular site), I would have to have a question about a particular thing (such as it's size). I would not get the "Full 5,000,000 word paper that describes every aspect". So, if the question is different, but still kinda related, go ahead and ask. Just don't go looking for the absolute or full definition of something.
Another fine example is a mouse event in programming (Im not going to focus on a language or anything). If you ask a question about, for instance, mouse dragging events, and then another about left-clicking, it's fine. If you just ask for mouse events in general, then ask about mouse events for blu-tooth, chances are that you are going to get flagged.
So, although I don't know the details, I think asking both of your questions within five minutes of each other is perfectly acceptable.
