Why is this Physics.Overlap triggering?

I'm running into an issue which appears to be a CharacterController incorrectly triggering a Physics.Overlap on another object when it is instantiated

Here is my code, stopped by the debugger. I added comments to show the values at the stopped moment

And here is the collider in question, as it appears in the debugger

It would seem that these colliders do not in fact overlap. The radius of 1.32 for the CharacterController should not put it within reach of the 5 unit radius of the Physics.Overlap. The world scale of the collider is 2.5, putting it at 3.3 radius max. Seeing as how the objects are 15.8 units apart, there's no way a 3.3 radius collider overlaps with a 5 radius OverlapSphere.

I should note that the commented out code near the top of the foreach fixes this problem. If I use that if statement to make the CollectFood function call only happen after being alive for .5 seconds, the function won't trigger. Any frame after the frame in which the collider is instantiated results in the colliders not touching, but with the same positions. It only triggers incorrectly on the frame it is created. The code that is instantiating the collider and it's gameobjects set the position on the very next line. There are no other function calls inbetween the Instantiate and me modifying the position.

I'd still like the collision detection to work without additional calculations and GetComponent calls to figure out it's age.

So why is the CharacterController overlapping on the frame it is created?
