While they obviously have different group IDs the display name are equal and users may have a difficult time to tell apart which one to use, e.g. for sharing.
For example a local group with both ID and Displayname "Musicians" is found which cannot be migrated (users from mixed user backend), then a group with ID "SAML_Musicians" is created, because "Musicians" was reported as group upon a user's SAML login. The displayname for both groups will be the same though.
