Whether you have to modify the screen removal procedure depends on whether the screen's mounting frame is still securely attached to the screen, or if the battery has separated the frame from the screen instead of the phones midframe like it's supposed to. Take a look in the gap to see if the mounting rails are visible, something like what you see in this picture.

If you can see them then you should be okay; that would mean the frame is still where it should be. If not, then the frame has probably started separating from the LCD itself. If that happens you'll want to remove the Pentalobe screws then when it comes time to create an opening for your pick you'll want to focus on the side opposite the gap in hopes you'll get between the screen frame and the phone. It's not a problem we usually see on the older phones, but newer ones it seems to be happening much more commonly that the frame comes off the screen so hopefully that's not what happened to you.
Good luck; let us know how it all works out!
