How often do professors check their emails on annual leave?

My supervisor is on annual leave right now. They said they'll take some time out to review my dissertation draft between the 15th and the 17th, they finished the review, but they attached the wrong file to the reply email so I don't know what changes to make. I sent a follow up email, but I don't know if they'll check their email while on leave and I wanted to know how often to professors check emails typically on leave. If they do not check their emails at all, I have also got my supervisor's phone number to use in case of emergencies, if this situation qualifies as one(they do not return to the university till after the dissertation submission date). Any help figuring out he right path to take in this situation would be grand. Thanks
