In software documentation, I recently read:

If you move a job to a different folder, you may also need to update configuration that was referring to that job.

But if you have a "configuration that was referring to that job" you need to update it. Not doing that will result in broken configuration and ultimately, broken behavior.

Is this use of "may need to" really correct? Is there a valid reason the documentation is phrased like this, instead of "…, you also need to update"?

Doesn't the current documentation through the use of "may" imply that there are situations where you're not required to update configuration because it handles the job move correctly?
