EDIT: There seems to be a lot of confusion in m question so let me pose this again.
My brother and I have separate APPLE ID's. I recently made a new Apple ID so I can download Pokemon GO and all was well, I signed out of the new Apple ID and went back to my own Apple ID and it worked perfectly (note: Pokemon GO has a different G-MAIL for everyone). The next day, my brother went onto the Apple ID that I created new yesterday and downloaded the APP as well and then logged back on to his account. At the moment we are both playing Pokemon GO, there will be an update next week; can we both log onto the APPLE ID that I made and update the app? Or can the update only work on one phone?
Original: I have a concern, I recently made a new gmail account in order to make a apple ID in a new country so I can download Pokemon GO – recently my brother found out the details and he signed into the account I made on his phone and downloaded the application as well. When the time calls for an update for the app, are we both allowed to update the application on our different phones or will it cause problems?
Thank you very much

As long as you are using different google accounts for Pokemon Go the fact that you are using the same apple ID will have no impact whatsoever on the game.
If you have changed Apple accounts since you downloaded the app then you may run into a problem when the app updates as it will ask for the password of the account is was downloaded under.
You can simply delete the app and redownload it under your current apple ID in order to have it under your current Apple ID instead of the old one. The fact that two people are using the same apple ID won't have any impact. It only matters that you have changed it since downloading it.
