No, because either way [50,60] or [50,50] the result is still the same. Doctrine returns no results... MongoShell returns numerous results.
I should also note that the following command
db.runCommand( { geoNear : "events" , near : [50,60], num : 1 } )
Returns

Is there a typo?
db.events.find( { coordinates: { $near : [50,50] }} )
should be
db.events.find( { coordinates: { $near : [50,60] }} )
