This is proof positive in Keith`s own words that the first 0-volt point
encountered by either forward or reflected wave is completely
ineffective in halting or abating progress of the waves.

The contradiction is obvious. Were energy flow or power reduced by SWR
zeros, you would not have multiple zeros along the line.
