I think you can pause a virtual machine while it is in any state. Some states (such as during boot or in a UEFI app) don't have the notion of sleep or hibernate and yet you can still pause them. This also applies to OSes that don't support sleep or hibernate. Therefore, Parallels is not using sleep or hibernate.
Like in OSX when you click the red close button on the windowed windows VM, what does that trigger in windows?
