The split /bin vs. /usr/bin is completely unrelated to the split between
*/bin vs. */bin.

/bin vs. /usr/bin is motivated by the FHS mandating /usr to be on a
filesystem of its own (and systems to be able to boot without /usr being
available), while the */bin vs. */sbin split is motivated by splitting
_system_ binaries off from ordinary users' $PATH.
