Remove unnecessary, tautological line

What does this MR do?

Removes a single, unnecessary line of documentation.

Are there points in the code the reviewer needs to double check?

I don't believe so.

Why was this MR needed?

The doc included a line which provided no information. It appears to be leftover from earlier edits.
