It doesn't make sense because you don't understand it, which is exactly why you should ask questions. Any IP not willing to take questions is a horrible IP, so yes, ask away, but realize there's a right way to ask a question and a wrong way. Additionally, don't be the guy who could easily find the answer in writing, but is too lazy to read the -1, 2-XXv3, etc. If you read something and don't understand it (including why it's done that way) then ask, but put some effort into finding and figuring it out yourself first.
