Yes, the magic here is, that the error dict contains "-level 0".
This does not exit the proc and thus, the outer try is also executed.

I have a vague memory that I was including a -level flag on the return statement in the past when "issues emerged". I shall keep my fingers crossed that I remember this discussion when strange things happen with this technique in the future.
