Question about window/door/mirror reflections.
I attempted to take a photo of two door paper flyers, it was a bright day and my vision was slightly impaired from the sun. I tried to focus on the center of the two doors. I took two photos. When I got home I realized I was in the reflection of the door.
1: One photo has me in focus but the flyers are out of focus.
2: The second photo has the flyers in focus (not perfect) but my reflection is out of focus.
Both photos were shot at 85mm, f3.5. The only difference being shutter speed which would not matter. 1/125 and 1/160th.
If the flyers are on the same "plane" as the door glass along with the reflection why would one or the other be in or out of focus.
I can understand this working with light but how does depth come into play in a situation like this?
I never took a selfie in the mirror and this was and accidental selfie. I will post both photos, they are both 100% crop.
Can someone explain this or give me some insight into this?

This obviously is the other photo.

A reflection is not a painting or poster.
In practical matters, your reflection is not on the same plane as the door, its focal plane is the same distance "behind" the door as you actually stand in front of.

This.
Light doesn't just paint a reflection on a plane, it bounces from the window and travels the distance you stand from the window. If you simply focus on the window plane, you are focused in the flyers or the dirt in the window, but not the reflection because it's optically behind the glass.
