We are all told that VSWR doesn't matter when using low loss

No, we are not all told that.
The active part of the transmitter output isn't 50 ohm.
That would cause half the power to be lost as heat in
the output stage. It's only 50ohm once it becomes a moving
wave in the transmission line.

In that case...

Half power is only lost when terminated to a 50-ohm load;
i.e. no standing waves. What happens when there's a
mismatch and reflected energy



I'll go stand in a corner...


A mismatch where, between the feedline and the antenna, feedline and source,
source and impedance seen at the input to the feedline.
