Shu"T Bnai Tziyon points to a gemara about two villages within techum
shabbos, where it was Yom Kippur in one and not the other, because that
was the last place the messenger had made it before sunset.  (I can't
figure out how that actually worked, but that is what the gemara says.)
He avoids the awkwardness of the situation posited in this clip by
positing that the line is not one-dimensional but is several miles wide,
and that the area inside the line has an official din of sofek, like
bein hashmoshos.
