Of course one does.  But that's completely irrelevant to the point
being made, which was that there's no actual sunset, and this lack
doesn't invalidate the shita that bein hashmashot begins at sunset.
Therefore the fact that there are places and dates when it never
gets dark enough for RT to consider it night doesn't invalidate his
shita either.

The exact opposite.  The sun begins to rise, but never quite makes it
over the horizon.  Noon is its high point, when it comes closest to
the horizon, so that is when we must count a notional sunrise and sunset
and change the date, just as we do in summer at midnight.
