The re-reflection is associated with destructive interference
toward the source and an equal magnitude of constructive
interference toward the load. The energy in the canceled
reflected waves is redistributed to a region that allows
constructive interference to occur, i.e. in the opposite
direction to the direction of reflected wave cancellation
toward the source.

Probably this is what you call destructive interference at the
trasmitter and constructive interference at the load.


At a Z0-match *point*, destructive interference *toward* the
transmitter and constructive interference *toward* the load.

It is akin to the passive elements of a Yagi causing
destructive interference to the rear and constructive
interference toward the front. What is the front/back
ratio of a Z0-match? :-)
