  Alpha output color problem

I noticed that when I output alpha transparency (+UA), colors seem to be
clipped/normalized strangely. This image illustrates it; the version on the
left is normal output, and on the right is with +UA. You can see that any
part of the image where a color channel would have a value greater than 1,
the color seems to be divided by that greatest value, rather than clipped as
usual. The result looks flat and dull.

Why does this happen? Can it be fixed?
