It CAN. If /etc/fstab content matches the labels of the
partitions, it matches them regardless of the disk they
are on (da[0123...] or ad[0123...]), so the disk can be
placed on any controller in any computer.

It does, which is obvious according to the explaination
given before. But it is not restricted to one machine.

Furthermore, it gives you the chance do change the name
for a device to something "human readable", e. g. the
descriptive name "usrfs" for "ad0s1e". In different
settngs, functional file system entry points may refer
to different device nodes, depending on the current disk
layout.
