Interesting behavior when flcking up on language roter setting

iOS & iPadOS

Hi all. I noticed that if you have the roter set to "language", only having set United states and english as your region and language something strange happens. I can confirm this with alex, so I'm curious. If you flick up or down, Samantha speaks something like: "English U.S. 200" I have no idea why it happens, has anyone ever had this? It's by no means a deal braker just something I wanted to ask. Thanks.
