That load will dissipate about 88.889W, and reflect about 11.111W back
to the source.

Likewise, the load will dissipate only 88.889% of the RE-reflected
power from the source for the same reason it dissipated only 88.889%
of the power in the original incident wave.

So even if the RE-reflection from the source is lossless, and phase-
coherent with the original incident power at the load, how does this
yield the 100W of load dissipation that you posit?

It's what happens while going from T0 to steady-state.

Pload = 88.889w -- 98.8w -- ... -- 100w
Pfor = 100w -- 111.11w -- ... -- 112.5w
Pref = 11.11w -- 12.3w -- ... -- 12.5w
