I'm sure Kovid can say exactly what occurs.
In practice this is what I see. It seems to do a quick analysis of the left and right (and top and bottom) for color matches then trims off what matches. I have never seen it trim perfectly to the edge of the picture and I have never had a cover able to trim a second time. At best this is a quick delivery of an imperfect attempt at trimming the cover.
If it won't do a trim it seems that it is not able to detect exact matches on each side that would allow it to trim. It would be nice to set margins on the cover image and then have it trim it, but that is not how it currently works.
