Change the Number of Rings screen doesn't mention voicemail

In https://www.xfinity.com/support/articles/change-number-of-rings-before-calls-are-forwarded we see on the example screen shown we can indeed change the number of rings, and indeed it works fine, but I am just curious: aren't there some words missing on that screen that should say these are the rings before sending to voicemail? I mean without the above help article, just looking at that screen, there is no way to guess that. Therefore the screen needs some more words added to it deep down in the software (not just to the above help article.)
