Wise Program Uninstaller license question

I have a question about the license for Wise Program Uninstaller Portable. On the update pages here, I see "Wise Program Uninstaller is freeware for personal and educational use." But, on their own site (http://www.wisecleaner.com/wiseuninstallerfree.html) I see "Wise Uninstaller is another freeware from WiseCleaner.com. All users are free to use it, update it and get the basic technical support on it."

Is the portable apps version more restrictive than the installed version, or might this happen to be a mistake...?

I'm not sure this is technically a support question, but it's the best slot I can find.
