All aircraft can point their nose away from the flight path.
In normal aircraft, once the airspeed has decreased too much,
and the angle of attack (angle diff between nose and flight path)
is too big, conventional flight control surfaces no longer respond
well.
Typically, aircraft handling will feel more sluggish, and if not
corrected, will result in total loss of control to the
aircraft. For the F-16, it has a tendency to stall with its
nose bobbing up and down.
Thrust vectoring comes in when conventional flight control
surfaces fail, and extends the limit of flight control greatly at
post-stall conditions. Eg, typically below 120kts the F-16
would be very very sluggish and unmanueverable, but with thrust
vectoring, or MATV in its case, I'd still be able to pitch and
roll.
