Yes, I understand how that works, but what is the point now that he says he can access those sites?

According to a Shaw article, it is possible to change one's IP address.

If your cable-modem is in "router" mode, the MAC address of the cable-modem is sent to Shaw's DHCP-server, and an IP-address is returned.

If you reconfigure the cable-modem into "bridged" mode, the MAC address of your computer (or your own wired/WiFi router) is sent to Shaw's DHCP-server, and a different IP-address will be returned.

Of course, setting the cable-modem to "bridged" mode may disable some of its "router" features.
