“Using a bore scope”

If I was using a bore scope I would not be checking for the ‘the cross hatch pattern’.when reaming a chamber the instructions read something like “Do not remove the reamer without rotating the reamer when withdrawing”. So, how did the cross hatch get into cylinder, we know the method for reaming is not back and forth but straight in and straight out while rotating. And then the other question, to cross hatch a tapered cylinder the cross hatch tool would have to have expander springs to force the tool against the taper while making/cutting the cross hatch??
