You can be added as a Guest, or as it seems is the case here, as a privileged user in other tenant's AAD instances with your OrgID.

Have you shared anything with them from O365? If so, that could be causing this behavior.
Azure AD automatically creates directories for accounts in domains as needed. If those firms ever decided to use O365 and/or Azure, they will take over admin responsibility of the directory. Until that happens, MS manages their directory automatically.The UI may be showing you those directories.
