Note the bit at the top of the Chicago section.
"US central time, represented by Chicago".
I read that to mean that these rules are not specific to Chicago, but
rather all of CST.
Likewise "US eastern time, represented by New York"
So, I read the US rules as setting the national standard, and then
the more regional rules to set the individual timezones before they
to were conformed universally to a national standard.
