Comment(by strk):

 It looks like the big difference here is the use of a cast.
 See debugging lines. Here's the geometry case:

 {{{
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:124] Entered function
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:129] Got lwgeom(type =
 6, srid = 4326, hasz = 0, hasm = 0)
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:130] Got typmod(type =
 6, srid = 4326, hasz = 0, hasm = 0)
 }}}

 Here's the geography case:

 {{{
 OTICE:  [gserialized_typmod.c:postgis_valid_typmod:124] Entered function
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:129] Got lwgeom(type =
 6, srid = 4326, hasz = 0, hasm = 0)
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:130] Got typmod(type =
 6, srid = 4326, hasz = 0, hasm = 0)
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:124] Entered function
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:129] Got lwgeom(type =
 3, srid = 4326, hasz = 0, hasm = 0)
 NOTICE:  [gserialized_typmod.c:postgis_valid_typmod:130] Got typmod(type =
 6, srid = 4326, hasz = 0, hasm = 0)
 }}}

 So the first part is the same for both (no mismatch) while for geography
 there's a second step going on in which lwgeom becomes visibly different
 from expected typmod.
