That marking is in the file zone1970.tab, which contains the following text:

And we're serious about this. We do not take any sides in territorial
disputes such as the dispute Russia and Ukraine currently have over Crimea.
The data for Europe/Simferopol, and the dispute over whether the file
zone1970.tab should list its country code as "RU" or "UA", are like the
data for Asia/Seoul, a city that zone1970.tab lists under South Korea
("KR") even though Seoul is claimed by North Korea ("KP") as an integral
part of its territory. There are similar disputes over other tzdb
entries, notably Asia/Jerusalem. Cases like these are resolved by the
general principle that the time zone database is intended for practical
use, and as a practical matter when people use time zone data they
typically want to know the facts on the ground even when these are not
the facts as they ought to be.
