When an explain is run on a $nearSphere query against a 2dsphere index we are incorrectly recording nscanned and nscannedObjects to be the "works" value rather than the actual # of index entries and documents evaluated.
This has been corrected for 2.8 as part of
SERVER-9986 but not for 2.6. As SERVER-9986 is a broad ticket covering much more than this issue I am entering a separate ticket to address 2.6.

SERVER-16402 $nearSphere with 2dsphere index (S2NearCursor) shows incorrect statistics
