As well as not all the reflected power being re-reflected, the forward
power measured by the coupler is not the first time forward power, but
the sum of all the re-reflected power, as well.

Actually, "delivered power" is pretty much what you are measuring.
Remember that reflected power is re-reflected by the source and adds
back into the forward power. So in your example, you are transmitting
1200 watts, having 200 watts reflected, then the 200 watts is
re-reflected by the source giving you the 1200 watts. Of course, there
will be transmission line SWR-related losses.
