Description of change

I made some minor edits to this documentation with #8651, and I just noticed that one of the sentences sounds awkward, so here's a fix.

Thanks. I fixed the commit message.

I'm not sure what makes this easier to understand.

[dguo]

I realize it's very minor, but it sounds quite awkward (to me) when I read it aloud because it uses a passive voice. Please feel free to close this though if you think it's fine the way it is.

Yeah, I really appreciate the contribution but I think I prefer the original

[dguo]

Fair enough. Thank you all for taking a look.
