If you reverse one winding on a Y connected three phase motor it won't work properly. The armature rotates with the magnetic field and with one phase reversed the magnetic field will not rotate at all evenly. In fact, the motor will probably take far more current than it would normally take.
Three-phase motors can be wired Y connected or delta connected. Some can be either, and the terminals of those are arranged so that it is really easy to swap between Y and delta, but really difficult to get the connection of any one winding the wrong way round. That is done because it's important to get the windings the right way round.
This is the usual arrangement.
The connections between W2, U2 and V2, or between W2 and U1, U2 and V1 and V2 and W1 are usually made with solid links, and the terminals are made so that all the distances are the same. Often, if the motor is delivered in a Y - configuration with W2, V2 and U2 connected, only two solid links are needed but three are supplied, to make changing to delta configuration easier.
When a motor is wired in Y or delta, swapping any two of the supply wires will reverse its direction of rotation.
On a single phase induction motor, there are two windings, and usually one has a capacitor in series. On one of those motors you could swap the direction of just one winding to reverse the motor. However single-phase induction motors are not referred to as Y connected.
