No, Emacs doesn't act on this as an event. What happens is that the
next redisplay after a window switch redraws the mode line in a
different face. The redisplay isn't triggered by an event (because
there is no such event), it is triggered by other means, mostly
because Emacs becomes idle. That could happen many seconds after the
switch, if Emacs becomes busy calculating something, for example.
