Yep, exactly. 

Of course, not much in a computer is truly random, but from a patch
author's and user's point of view, in the end the order of executing
non-local connections appears "random". If you look at a patch you
built one week ago, do you remember the order you made the
connections?  And maybe you copied and pasted some stuff, used Ctrl-Z
or something else, which may have changed the order without you
knowing it.

That's why I really prefer to call this "random" or "undefined" or
"ambigous" in a non-scientific, practical sense. It may work now, but
may break tomorrow.

Also one should be aware, that very often the actual order of
execution of signal cords doesn't matter. It does matter in waveguide
stuff or in comb filters where you need these small delay times.
