Read the IM example notes
   Composite Geometry/Gravity Settings
          vs   Layer Canvas/Page Offsets
  http://www.imagemagick.org/Usage/compose/#geometry

Basically gravity is used by two image alpha compositing
for adjusting how IM interprets 'geometry offset'
It is NOT used by 'layers' which only uses an absolute
virtual canvas or 'page' positioning.

As such you need to give your image a 'page' offset
to position it where you want it.

alternatively.  'layer' your three images, then
+append the right image to it!  May be more logical.
