nonsensical wording in docs for watch

[Luna5829]

in the docs for the watch function, specifically under the definition for "step",
it says "time to wait for new changes in milliseconds, if no changes are detected in this time, and at least one change has been detected, the changes are yielded."
I am specifically talking about the "if no changes are detected in this time, and at least one change has been detected" part,
it makes no sense, it's basically saying, "if no changes have been made, and a change has been made"which makes 0 sense.
I'm assuming you wrote those docs but if you didn't idk lol
It'd make more sense for it to just simply say "if at least one change has been detected"
making it be "time to wait for new changes in milliseconds, if at least one change has been detected, the changes are yielded."
which is a lot clearer and actually makes sense
it's possible I'm just misunderstanding what it's suppose to say but idk
