Yes. What you suggest would short out the winding, causing it to draw
huge current from the wall socket. it will either destroy the transformer
or trip a breaker in your fusebox. The direction of each winding is
absolutely important, as it determines the phase relationship of the
AC wave. This is how you get 240 V across the two hot terminals
in the fusebox, but 120 V from neutral to either hot one. That is
exactly how the pole transformer is wired - a center-tapped winding.
Don't try shorting the two hot wires in the fusebox together to get
more 120 V current. It will explode.
