It is a pointy edit because you are removing information not because you believe it not to be factual, but to make a point, that if you're not allowed to add material without a citation from a reliable source when another editor disputes it, then everything must be sourced.  If you were removing it because you actually did not believe that the Tappan Zee Bridge connects Greenburgh to Orangetown, then the edit would not be pointy, but you're only doing it to make a point about "consistency" - and that is the very definition of pointy editing.  Cut it out, please.
