Hello Luther.
What is going on is way more complex than you think. You have to find the part of Matt Neubergs book "AppleScript the Definitive Guide" where Berkowitz is referenced, it is around a discussion of the open and run handler. Berkowitz nailed it.
You see, the error statement triggers the run handler ... So you are really jumping into the run handler in the middle of your open handler.
I guess something similiar will happne if you can't open a webloc file with the open handler.
Control is passed over to the run handler/implicit runhandler, and nothing more happens if you havent taken the measures described in Matt Neuburgs book.

(And, coincidentally, the webloc file was NOT opened in Safari!) So even though this kept the webloc from opening, there's still no access to the file itself. Clearly, the 'on open' handler does not treat webloc files as regular files.

I can't figure out what dictates which webloc opens, but it's not the alphabetical order of either their filenames or URLs nor the chronological order of either their creation or modification dates.
