I believe both photos must show the cap while screwed onto the bottle. In the photo of the new cap, the orange stuff is the bottle.
The picture shows the screw threads of the bottle opening meeting the threads of the cap. And you can see some asymmetry where the part on the left side of the bottle opening is vertically lower than the part on the right side, which is consistent with the thread being a spiral shape.
