How does the Semantic Index refresh/index on files actively in development? Many Versions...

Files in SharePoint and OneDrive will be available for the creation of our tenants Semantic Index for Copilot. A question came up on how this indexing will work on files in active development.  Say there are many versions of the same file available.  How will the indexing choose what to update?  What if the content in the drafts is incorrect, will it return incorrect information with Copilot?

Thank you!
