Hi MxxCon, 

The honorary name only applies to the intersection, despite the inclusion of "Boulevard". Below is an article highlighting the intersection naming back in 2017[1]. I was following OSM Wiki guidance [2][3] on how to add names for junctions. But please let me know if this is incorrect - I assisted the Queens Memory Project in adding a handful of these, so I'm happy to make corrections to all of them if needed. 

There is also precedence of this being done elsewhere in NYC, which I had checked for before adding this name and others. [4]
