Managed Windows laptops with DirectAccess are configured to keep a synchronized copy of your Home Directory copied to its hard drive. DirectAccess allows your laptop to access your Home Directory in SU's cloud when it is connected to the Internet. The synchronization is not instantaneous. It could take as long as 2 hours for the sync to happen on its own. It's better practice to force a sync rather than closing the laptop's lid and hoping it sync'd.
The Sync Center is probably hidden. Press the "Show hidden icons" arrow to reveal it.
When it's done the Last sync on date should be in the recent past. If there are conflicts go ahead and try to resolve them. Usually the newer file is the one you want to keep. If you're in doubt save them both.
