It separates the case when fork fails and when fork succeeds. You can
even move error-processing code to something like xfork().

First, we die if fork failed.
If fork succeeds, we continue and have branches for child (pid == 0) and
parent (pid == child).

With switch, we have branches for failed parent, child and suceeded
parent, in this order.

Also, the code is obviously shorter.
