" You will come to the same conclusion if you normalize the chart to 100
ohms,
the new source impedance and re-plot.

The Z0 of the transmission line has not changed to 100
ohms so normalizing the chart to 100 ohms is not valid.

It is just as valid as using 50 ohms, and the result is the same, a changing
vswr.

I see you have not commented on the main point of my post, that being that
the smith chart shows a changing vswr when you change the source impedance.

Hint: transmission line transformers would not work if the vswr did not
change.
