I think you might be right. This might be oversight, unless
checkVisibility() uses the screen coordinates (which would be somewhat
pointless).

I'd say, do a git blame, and see which commits last touched it, and
see if it explains some special reason why it is the way it is. If
there's none, please go ahead and change this, and test if it works.
If it works to whatever extent you can test, go ahead and commit it.

You might get a quick answer on #kde-devel -- there are some people
who know QML very well.
