If I understand you, you want to know if changing the exhaust to the same end as the firebox makes a reverse flow. If you do noting to force the smoke to travel down to the other end and then travel back over the meat to the exhaust, no it won't make it a reverse flow. You will then have a no flow smoker.
I don't understand his tuning plate comment or solution.
