That page says: "Two Thunderbolt / USB 4 ports with support for: * DisplayPort * Thunderbolt 3 (up to 40Gb/s) * USB 3.1 Gen 2 (up to 10Gb/s) * Thunderbolt 2, HDMI, DVI, and VGA supported using adapters (sold separately)" The wording isn't terribly clear, but given this snippet from Wikipedia's USB4 page: "The USB4 specification is based on the Thunderbolt 3 protocol specification.[2] Support of interoperability with Thunderbolt 3 products is optional for USB4 hosts and USB4 peripheral devices and required for USB4 hubs on its downward facing ports and for USB4-based docks on its downward and upward facing ports." I'd say it's a USB4 port that is also compatible with TB3 and USB 3.1 gen 2.
