the difference in behaviour is controlled by the 
NSADDIMAGE_OPTION_WITH_SEARCHING flag to NSAddImage. without it 
NSAddImage only tries to load the file it was given the path to, with 
it also searches through the standard dyld library directories & 
DYLD_LIBRARY_PATH etc:

man NSModule:

        The other options of NSAddImage are as follows:

        NSADDIMAGE_OPTION_WITH_SEARCHING
               With this option  the  image_name  passed  for  the
               library  and all its dependents will be effected [sic] by
               the various DYLD environment variables as  if  this
               library were linked into the program.

Cheers,

Daniel
