When you type this manually, you're effectively executing this:
execute 'norm! dd' | execute 'norm! k' | execute 'norm! P'
And this indeed doesn't stop.

Yes it is. The beep that is issued is a clear indication of the error.

Yes, it is intended, and it's very helpful to abort (recursive) macros. And the
reference in the help is exactly what you've quoted. Sorry that some Vim
peculiarities are so hard to discover, but I guess that's the price one has to
pay for such a powerful editor.
