Quote from Windows 10 tip: Temporarily delay the Anniversary Update | ZDNet
On August 2, Microsoft's update servers will begin delivering the Windows 10 Anniversary Update (version 1607) to current installations of Windows 10 that have been running for at least 30 days.
Even that in my opinion supports this. To be sure a Windows 10 user who used the free upgrade offer during its last month cannot roll back to their 7 or 8.1, they will only get 1607 upgrade after their roll back period is ended.
