In a conjugately matched system using lossless transmission line:

The source can be "matched" to the input of the transmission line feeding
the load but not be conjugately matched to the transmission line/load
combination.

Note that I specified an ideal lossless transmission line.
In a lossless system, if a conjugate match exists anywhere,
a conjugate match exists everywhere. My assertion was a
conceptual statement about an ideal example.

Conversely, we can have reflections present at the source-line interface
for conjugate match conditions.

I was also assuming a 50 ohm source with a 50 ohm Z0-match in a
lossless system. I should have specified such. Here is what I
had in mind.

XMTR---50 ohm coax---+---1/8WL 300 ohm twinlead---(97.3-j283.8)

There is a (close enough) 50 ohm Z0-match at '+' :-)
