You were flattening the list of circles, thus loosing the link they had to the surfaces they were generated by.

The shift path component, and the graft on Trim ensure that Trim gets clean data structure (4 surfaces=4 branches, 4 sets of circles=4 branches) .

Then you sort the trimmed surfaces by area (not interested by little circular cuts) and get the largests (first item of reversed list).
