The power delivered to the load really is forward power minus reverse
power. You can see that by imagining that you disconnect the load
completely (infinite impedance) or short it out (zero impedance). That
means no power can be absorbed by the load.
The wattmeter reads equal forward and reverse power, so that forward
minus reverse equals zero, as it must.

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.
