Wifi Backwards Compatibility for ASRock X570 PHANTOM GAMING 4 WIFI ax mobo

[Eric10543]

I recently found this motherboard on pcpartpicker.com for a very good price (153$ USD) and it comes with an included Intel Wifi 6 adapter (AX200 or AX201, wouldn't specify) and antennas. On AsRock's product page it states that this card is "Supports IEEE 802.11a/b/g/n/ax" but it left out 802.11ac, which I currently have at home (802.11ax upgrade later down the line). On Intel's page, however, it states that both their AX200 and AX201 wireless adapters are backwards compatible with the 802.11ac standard. To add to the confusion, I sorted X570 motherboards on pcpartpicker by wireless adapter (802.11a/b/g/n/ac/ax, 802.11a/b/g/n/ac, and 802.11a/b/g/n/ax were the filters I sorted by) and this motherboard came up as "802.11a/b/g/n/ax", clearly stating that the card doesn't support Wifi 5. I'm confused, and the images aren't high-res enough on AsRock's product page for me to get a serial number from the M.2 wireless adapter. If someone could shed some insight on this issue that would be tremedously helpful.
