Earlier quoted context omitted.
I just want to point out that there are large portions of New York that are not New York City
Pedantically, the name of the city is just New York. Given the context ("or San Francisco"), I think it's clear he didn't mean to include Buffalo. "New York or California" would have meant the entire state.
Wikipedia even notes the differentiation is important.
"The city is referred to as New York City or the City of New York to distinguish it from the State of New York, of which it is a part"
