Sorry, I couldn't resist.
It keeps particles from going in to the manifold and clogging your 1/4" lines. The drip isn't identical. Although the drip seems to depend more on the height of the drip line as opposed to where in the manifold it is located. The point of the circle manifold is to get even pressure. If it was just a straight tube with a cap on the end it would have more uneven pressure i hear.
