End of Sale / End of Life

https://www.cisco.com/c/en/us/products/collateral/switches/small-business-220-series-smart-plus-switches/220-series-smart-switches-eol.html

"Cisco announces the end-of-sale Cisco 220 Series Smart Switches. The last day to order the affected product(s) is July 30, 2022."

Which is confusing, as this would seem to indicate that the replacement for this document is the Cisco 220 switch?
