can china southern book a hotel for overnight stay before an international connection in guangzhou airport?

On CS's website, in the guide to GZ airport, it says,

"3. Free Accommodation for Overnight Transfer

If you have to connect flight the next day at GZ, you may enjoy our overnight free hotel service and free bus transportation between the airport and hotel. Please turn to our transfer counter for further information."


Seems a bit odd, but that is what it says.
