In my third example, where does the other 10 watts of reflected power
go? If it goes to the load and back, why does it reflect off the source
resistor?

Roy, none of my textbook authors think the reflection model
is flawed. Walter Johnson goes so far as to assert that there
is a Poynting (Power Flow Vector) for forward power and a
separate Poynting Vector for reflected power. The sum of those
two Power Flow Vectors is the net Poynting Vector.
