I must have overlooked this fact. Where it's written?

What I said comes from http://doc.qt.nokia.com/latest/signalsandslots.html
"If several slots are connected to one signal, the slots will be
executed one after the other, in the order they have been connected,
when the signal is emitted."
and as I said, was added in 4.6 docs by commit 0ea19cf0 -- before it
showed "undefined".
