Boolean with offset does not work on complicated fillet surfaces

In this document there are two Boolean. The first leaves out the two surfaces that cause a failure. The second only has the two surfaces that cause the failure.
The offset of 0.015" is being used. Without the offset it works.
Initially I selected 0.015" offset all given that is the desired result.
Why doesn't this work?

The reason the fillet is "split" as in @steve_shubin 's image above, is that the original geometry (before the fillet) has four edges sharing a single vertex.

I don’t know why the boolean with offset failed.
But if you’re interested in a workaround,
see the document below.

I got it to work by using a single boolean — the way you wanted it to work
I used REPLACE FACE to eliminate the lines shown below. Then I was able to use a single boolean with offset on ALL THE FACES.
