The function oe_get_top_module was added to allow users to define multiple
module definitions. For example:

// File A.idl
module M {
    interface I

// File B.idl
module M {
    interface J

The function oe_get_top_module looks like:
oe_get_top_module(OE_IFR, ID, Name, Version) ->
  case orber_ifr:'Repository_lookup_id'(OE_IFR, ID) of
    [] ->
      orber_ifr:'Repository_create_module'(OE_IFR, ID, Name, Version);
    Mod  ->

Hence, if module M not have been registered before it will be created,
otherwise the existing definition will be used.

Have you registered the included IDL-file as well (i.e. types.idl)?
If you look in the oe_XXX file the function include_reg_test/1 states
which file you must register first.
