Question(s) RE: May 1st Zero-Day Vulnerability Patch Release(s) and WSUS

Question
-
1.Will WSUS properly handle the zero-day patch (KB2964358 & KB2964444) distribution to machines that are either in a “not installed” or “pending reboot” state for the April’s IE cumulative updates (KB2936068, KB 2925418, KB2929437, etc.) ? e.g. if both the IE updates from April and the zero-day patches are downloaded to a workstation simultaneously (or between reboots), will the workstation handle the install(s) properly?
2. Can more details be provided for the “potential compatibility issues” that could arise happens if the zero-day patches get installed before April’s IE Cumulative updates?

A machine in a "Pending Reboot" state will not install updates. Period. It must be rebooted.
If the updates are downloaded *simultaneously*, both updates will be installed and the system will reboot once. This is how Windows Update has functioned for the past fourteen years.
There are no "potential compatibity issues"... either the Cumulative Security update supersedes the zero-day patch, or it doesn't. In the former, only the CumSecUpdate is required; in the latter, both are required, and not only does the installation order generally not matter.. you can't actually control the installation order anyway -- unless you explicity try to... and what would be the point of that?
