Can you explain why that is the one advantage (BC)/revers on localizer,

why that is so?

An HSI is like a CDI you can spin around. When shooting a back course
it is effectively upside down, cancelling out the reverse sensing.

Yes, thanks.
But there is no such thing as "reverse-sensing" on the localizer. If
perhaps the current common teaching of localizers and CDI was corrected then
we that selling point of HSI is dropped.

The CDI needle points to the color sector you are in. On some (older) nav
heads the blue and yellow sectors were indicated. So, no need to look for
reverse sensing/etc, just look at the approach chart, look at the needle and
you will know where you are relative to the course. Nothing could be
simpler.
