Although this is the Beginners Questions forum let's try this.

Here's a diagram from a currently unreleased interactive widget on PhotonsToPhotos:

Mark,

Not to scale but this crude annotation might help.

So it's whether the red and blue cross the image plane (I) inside the Circle Of Confusion (COC).

FWIW, your approach would imply equal distances behind and in front for Depth Of Field (DOF) and we know that definitely not so.

And your approach can't explain how to get the hyperfocal distance when focused at infinity.
