This still schedules La Rioja for DST, it just drops "S" from timezone
abbreviation. The same mistake is with San Juan and Catamarca.

I thought Jujuy was expected to introduce DST, so why this change?

So are they actually in WART zone? Seems to me that the bylaw just
allows the governor to pick more suitable zone, so I'm inclined to leave
them in -3 and just wait for a magazine article to show up with
definitive answer. (But honestly I have no idea if the -4:00/1:00 is
some kind of idiom, maybe it suits exactly this kind of situation.)
