That merge only works because you happened to get lucky, and have
portage merge coreutils in a particular manner (/usr/bin/uname
installed before /bin/uname).  If portage had installed /bin/uname
first, you would have ended up with a /bin/uname symlink pointing to
/bin/uname.  The same is also true of basename, chroot, cut, dir,
dirname, du, env, expr, head, mkfifo, mktemp, readlink, seq, sleep,
sort, tail, touch, tr, tty, vdir, wc, and yes.

I myself am currently running a system with the opposite merge (/bin,
/lib, /lib64, and /sbin are symlinks to /usr/bin, /usr/lib,
/usr/lib64, and /usr/sbin) although I do not yet have the sbin -> bin
merge yet.  I added a post_src_install and post_pkg_preinst hook in my
/etc/portage/bashrc to ensure that there are no conflicts before the
package is merged and a pre_pkg_setup hook to disarm gen_usr_ldscript
(so as not to create a conflict).

The only two packages I have installed that I had to modify to make
this work were coreutils (as noted above) and plymouth.
