[mythtv-users] HD PVR and IR transmitter for channel change (why)

Sorry if this is remedial, the wiki does not appear to address the
If the setup for an HD PVR from cable STB is
STB --> [composite] --> HD PVR --> [USB] --> Myth BE
Then the wiki appears to jump straight to a conclusion that the IR
Transmitter channel change wiring and setup is
HD PVR --> [ir emitter] --> STB
with a lot of instruction about how to ensure modules/kernel and myth
setup are done.
My QUESTION: there seems to be a leap or assumption made that this is
the best/correct IR transmitter setup to channel change on the STB.
Can someone please elaborate on this? Are there other options or at
least reasons why this approach is favored? My gap in understanding is
that this is not similar to how IR transmitting is done when capturing
from STB -> PVR 550/150 or other setups. Why is the HD PVR IR
Transmitter favored over IR transmitting from the BE?
