fusion cloud API understanding update timestamp

Summary:

i need to ingest some data using the API at this endpoint: "logisticsRestApi/resources-int/v2/repetitionSchedules" . this returns me json that contains links to other endpoint which retrieve more data like "/logisticsRestApi/resources-int/v2/repetitionSchedules/{repetitionScheduleGid}/stops". (the repetitionScheduleGid comes from the intitial call)

now my question is if a change is made to the data in the /stops endpoint or any other one of the nested URLS, will the update timestamp that is in /repetitionSchedules be updated? or do i have to iterate over every URL and check it's update timestamp?

example json output from /repetitionSchedules (truncated):

{
"hasMore": true,
