It’s kind of difficult to trace what’s happening here, so let’s split up the state for each key. Note, though, that this is just a visualization aid; the full state is still being transmitted as a single unit.
When USB 3.0 came out in 2008 it had a max speed of around 5 Gbps.

When USB 3.2 came out in 2019, the 5-Gbps USB was rebranded again to “USB 3.2 Gen 1,” the 10-Gbps version became “USB 3.2 Gen 2,” and the new 20-Gbps spec became—you guessed it—USB 3.2 Gen 2x2. … Wait, what? The “2x2” refers to running two 10 Gbps lanes of data simultaneously and … you don't need to know all of this. Many hub manufacturers have given up on names, labels, and symbols. They've just started printing the maximum speed next to ports directly.
