From https://blogs.technet.microsoft.com/wsus/2017/08/04/improving-dual-scan-on-1607/:

‘As mentioned in Demystifying “Dual Scan”, configuring a combination of policies on Windows 10 1607 can result in those clients automatically [and unexpectedly] scanning against Windows Update, as well as subsequently ignoring deployment instructions from WSUS. We heard feedback from on-premises administrators that they needed the deferral policies only for ad hoc scans against Windows Update, a scenario which was not supported. The previous post mentioned a summer release of a policy on 1607 that would address the issue, and we are pleased to announce that this policy has arrived.’

I think I mentioned already in another discussion the side effects of using Group Policies from conflicting groups, the WU policies and the deferral policies at the same time.
It is a good thing that this subject is getting its own thread which should be made sticky for reference.
