More example `same hierarchy` in path templating

We can't describe different templated name with same hierarchy.

Templated paths with the same hierarchy but different templated names MUST NOT exist as they are identical.

But I can't understand what the same hierarchy means.

We can't describe these path templates

  /pets/{petId}
  /pets/{name}

But we can describe these?

  /pets/{petId}
  /pets/{name}/hello

These depth of the hierarchy is different but these is different templated name in same depth of hierarchy.
When we get /pets/1/hello we can match bottom paths and name=1.
These is partially the same, but the whole is different.

So I want to add more example to this section.

Trouvez la section de la spécification contenant la règle citée « same hierarchy » et lisez les indications environnantes sur la mise en modèle des chemins. Ajoutez un exemple clarifiant pourquoi /pets/{petId} et /pets/{name} sont en conflit, tandis que le chemin plus profond /pets/{name}/hello est différent, puis vérifiez que la formulation correspond à la règle.
