White rim trail permit specific question?

I bought a back country permit today for October. When I reserved it they asked what my entry and exit points would be. I was running out of time and just guessed and put the wrong exit point in my reservation. Question is does the exit point I put even matter?

 

I don't have any personal experience in Moab but I do watch Trail Mater on YouTube. I would suspect that the entry and exit points are requested to assist in finding you if you go missing.

• You will also be required to select the entry and exit point for your trip. Be sure to look at a map and plan your entry and exit points beforehand!
• Be sure to enter important information such as your vehicle and emergency contact information. This information helps rangers in emergency situations.
• You can modify your reservation, with the exception of the alternate trip leader and trip start date, up until your permit is issued by logging into your recreation.gov account, or by emailing the Backcountry Permit Office: canyres@nps.gov.

 

Cool I'll modify my exit point. Thanks
