At the London Covent Garden Apple Store, I was told I could use the USB to share a disk drive as well.
Unfortunately, this is NOT correct. The AirPort Express will NOT support a hard drive at the USB port.
What version of the AirPort Express do you have?
If you do have the "new" AirPort Express with both a WAN and LAN port, then you should be able to connect a NAS....or any other Ethernet device.....to the LAN port. Here, I am assuming that the AirPort Express is acting as the "main" router for your network.

Is the AirPort Express acting as the "main" router for your network? If yes, then the Ethernet port behaves as a WAN port
If the the AirPort Express is configured to "join" your network using a wireless only connection, then the Ethernet port behaves as a LAN port.

Airport is used just to build a wi-fi, i.e. not to access the Internet or join an existing Ethernet network.
Would this qualify it as "main router"?
I'm just using it to share a printer and would like to use the Eth port to connect the NAS only.

I wonder when they changed that. My Express and the equipment connected to the switch behind it will be unhappy to hear that they should not be working.

The OP has a single port AirPort Express connected to his modem to provide wireless service and he wanted to connect another Ethernet device to the same Ethernet port on the Express that is being used by the modem.
If you are doing the same thing as this, please tell us more.

for the avoidance of doubts, in my original question: I'm not currently using the Ethernet port, as the Airport is only used to share a printer through the USB; I'm trying to connect a NAS to the Ethernet port.

This would mean that the AirPort Is creating a wireless network, so the WAN port would be connected to your modem...and it would be the main device on your network.
I now understand that you are not using the AirPort to "build" a wi-fi.
Look for the model number on the side of the AirPort Express that you have and post back with that information.
What operating system are you using on your Mac?

there is a misunderstanding about building or not a wi-fi.
I have no modem attached to the Airport; I use mobile broadband pay as you go, which the Airport has nothing to do with (I keep it turned off when I surf the Internet).
I use it to share a USB printer through the Airport wi-fi, i.e. I turn the Airport on if I have to print a document and connect to the Airport wi-fi. Plus, there is one spare Ethernet port.
What makes the port WAN rather than LAN?
A port should be passive? Is there any pre-configured SW settings?
Model Number is A1264
Snow Leopard just installed on MAC, plus I will have to connect also PCs.

On the Mac......
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Express
Click Manual Setup
Click the Wireless tab below the row of icons
If the AirPort Express is fully compatible with your network, check to make sure that there is a check mark next to "Allow Ethernet Clients"
Click Update to save any change you make and let the AirPort Express restart
Temporarily, turn off the wireless on your computer and connect it to the AirPort Express using a spare Ethernet cable to test to see if you can get an internet connection.
If you can, then the NAS device has a good chance of connecting.
