A segment from the branch versioned scenario documentation is misleading and requires adjustment.

Workaround

Use this alternate documentation:

• Manage branch versions—ArcGIS Pro | Documentation
  • If a strategy in which no one directly edits the default version is chosen, the geodatabase administrator should set the access level of the default version to protected. With the permissions set to protected, any user can view the default version, but only the version administrator can edit the version directly and post edits from other versions. To change the default version to protected, a database connection must be used that is established as the geodatabase administrator.
