This could have to do with a misinterpretation of meep coordinates. With the libctl interface, a 10x10 cell will have its center at (0,0), its bottom right at (5,5), and its top left at (-5,-5). The C++ interface is a bit different, with the origin corresponding to the top left corner of the computation domain.
This behavior is "sort-of" documented here: http://ab-initio.mit.edu/wiki/index.php/Meep_C-plus-plus_Tutorial#Differences_from_libctl I say "sort-of" because it only defines the center and range for each interface, but not the orientation.
