No, it is not doing the right thing.

Scribus does not have the ability to flatten transparency for PostScript
or for PDF <= 1.3, neither of which support it. Unless something changed
quite recently, the transparency attribute is ignored.

Hopefully moving to a Cairo renderer will permit flattening to be
performed at some point in the 1.3.x series.

The only real workaround is to output PDF 1.4 or greater and print from
Adobe Reader or a similar app. Scribus's PDF output is much better than
it's PostScript output anyway.
