The following query:

SELECT ?item WHERE { ?item wdt:P31 wd:Q515 . FILTER(?item = wd:Q62) } LIMIT 10

outputs Q62 (San Francisco) as expected but this query

SELECT ?item WHERE { ?item wdt:P31 wd:Q515 . FILTER(?item = wd:Q60) } LIMIT 10 outputs nothing given that at the time of writing Q60 New York City is also an instance of a Q515 city.

I expected that both Q60 and Q62 behave the same.
