The whole story of having to flash to a stock rom is false. It just has to be something different. If you are staying with in the same build number it is wise to change the build version then flash the new version.

So say you have the newer 6.5.x (start on the bottom) and you are going to another 6.5.x build. This is when you would flash say the older 6.5 ( start at the top) before flashing to the newer 6.5.x build. It just makes sure that there is nothing left in the ram from the previous flash. If there was and you flashed basically the same build on top of it, it might not properly overwrite the old information.

I have never even bothered to do this and I can't say I have ever run into an issue.
