Automation Triggers with Deal stage not changed



I have been creating new email automation to send out reminders when someone has been in a certain stage for a week.

I am using the instant conditions of Deal stage is __ and Deal stage has not changed. With then a delay of 1 week. Then the email template is sent.

My question is if a deal is triggered by this automation, but is still not moved/changed stage after another week would it be triggered by the automation again? Or is it only once per deal?
