They don't have to, but having them all touch the wall is an easy rule to make them all swim the same length. Also, using the wall to push against gets them back to speed a lot faster than if they'd turn just in free water.

When bullets bounce or are reflected off a wall, it is known as a "ricochet." This occurs when the bullet strikes a hard surface at an angle that causes it to rebound in a different direction. Ricochets can be unpredictable and dangerous, posing a risk to both intended targets and bystanders.
Sound bounces off walls due to the reflection of sound waves. When sound waves hit a wall, they bounce back in the opposite direction, creating an echo or reverberation effect. This happens because the wall's surface is hard and smooth, causing the sound waves to reflect off of it rather than being absorbed.
When a ball hits a wall, it bounces off due to the conservation of momentum and energy. The impact of the ball hitting the wall compresses the ball's surface, storing potential energy that is then released as kinetic energy when the ball rebounds back.
Because it lets the team know it's for them to keep the puck going and making it into the goal
When sound waves hit a wall, they bounce off and create echoes in a room. This can affect the acoustics by either amplifying or dampening certain frequencies, leading to changes in how sound is perceived in the space.
