From http://download.autodesk.com/us/fbx/FBX_SDK_Help/files/fbxsdkref/class_k_fbx_x_matrix.html:
Matrices are defined using the Column Major scheme. When KFbxXMatrix represents a transformation (translation, rotation and scale), the last row of the matrix represents the translation part of the transformation.
My understanding of algebra is that the column major scheme has the translation on the last column, not the last row. Perhaps what was meant to be written was that indices 12 13 and 14 represent the translation?
