That's an equality, not a definition.
No, it is from the IEEE Dictionary.
The IEEE Dictionary shows the relationship between energy passing a
point and the equivalent in units of power. That is a fact.
There is a real world experiment that you can perform to
prove your concepts are incorrect.
TV XMTR--tuner----2 uS long 600 ohm line---75 ohm TV RCVR
The first ghost will occur 4 uS after the primary image.
This can only be explained by part of the energy in the
primary signal changing direction and momentum at the RCVR
and making a round trip to the tuner and back to the RCVR.
In order to make that round trip, the energy in the signal
had to change direction and momentum at the tuner. (There are
no reflections between the XMTR and the tuner.)
Likewise, the second ghost will occur 8 uS after the primary
image, indicating four reversals of direction and momentum
of the energy contained in the second ghost.
Proving that reflections actually exist, and that when all you have is a
hammer, everything looks like a nail. Are you trying to prove
something, or disprove it with your ghost story? You're not generating
a clear picture. ;-)
