ontology import: classes of imported ontologies do not appear in target ontology class list

When importing an additional
onto = get_ontology("my_ontology.owl").load()
list(onto.classes())
... classes of onto are listed
# check imported ontologies - should be empty
onto.imported_ontologies
>> []
another_onto = get_ontology("my_other_ontology.owl").load()
list(onto.classes())
... classes of another_onto are listed
onto.imported_ontologies.append(another_onto)
# checking ontology import
onto.imported_ontologies
>>[get_ontology("my_other_ontology")]
list(onto.classes())
... still only classes of onto appear, but not of another_onto
Intuitive behavior would be: here all classes should appear.

I have the same question with you. And I have no idea how to solve it

I think the issue with the above may be that onto
and another_onto
have different namespaces, and because of the different namespaces they classes cannot be placed into the same ontology. I.e. if list(onto.classes())
is [namespace_1.class_1, namespace_1.class_2, etc]
, it makes sence that namespace_2.class_1, namespace_2.class_2 are not placed in the same list.
But then what is the supposed function of onto.imported_ontologies.append(another_onto)
?
