Comment(by strk):

 So, postgis_addbbox uses lwgeom_add_bbox over a deserialized geometry,
 which is then re-serialized, while ST_Equals uses gserialized_get_bbox_p
 over the serialized geometry.

 lwgeom_add_bbox in turn calls lwgeom_calculate_gbox_p.
 gserialized_get_bbox_p also calls lwgeom_calculate_gbox_p.

 This is the theory. But something goes wrong in between.
