Yes, you are incorrect in that assertion. Email does not truly "sync" as do the PIM resources, it is a reconciliations of actions.
In order for reconciliation to occur the email must move within the information store so that Desktop Manager can find it. When you delete an email it is simply moved into the deleted items folder, DM sees this and removes it from the device.
When you move an email into a PST before DM can reconcile it, it will take no action on that message on the device, because it cannot find any trace of it in the information store.
