Whenever you are going in or see someone coming in after you IMO you are obligated to letting people know where you are. It's a matter of safety. Good bright flashlights are a must. You see his and he sees yours. Most times if you are in first and someone shows up and you are shining them they will be the one to relocate.
As you weren't sure of his position you made the right choice to not shoot.
