Yes and no. It depends. You need (1) to have focus on OS X before hitting cmd-tab, else the cmd-tab is given straight to the VM as a Windows-tab, actually switching between windows tasks inside the windows vm. You also need (2) to have set up Parallels and the VM settings such as to display Windows application icons in the Mac OS X dock, else the cmd-tab pressed from Mac OS X will only see Mac OS X application and the Parallels application itself.
What would be really powerful is this: either with OS X focused or a Windows VM focused, at any time so, pressing cmd-tab is handled on the OS X side and allows to roll between all OS X application + all running Windows VM applications (not the VM themselves, but the applications running in the VM) and have this happen wether or not the user chose to have the windows application to be displayed in the dock or not.
In that ideal world, each windows VM would have a new configuration switch to choose wether the cmd-tab is to be intercepted or pass through to Windows as Windows-tab.
