After more than 24 hours this functionality started working even without running Set-SPOTenantSyncClientRestriction with -Enable parameter (despite MS Support saying that the functionality is available only with on-prem AD).
However, there still is an issue as this feature was implemented only half way. Blocking desired file types from being uploaded into the cloud storage using the OneDrive Sync client is working fine, but the Set-SPOTenantSyncClientRestriction cmdlet does not apply to uploading files using the Web View and user can upload the files using the browser. MS Support said that the web access to OneDrive cannot be disabled while keeping the sync client enabled. Will provide another feedback for the half solution issue.
