Those devices refer to disk slices (hence the 's' at the end), and slice
number two refers to the entire disk by convention (but not necessarily;
for more information see
http://docs.oracle.com/cd/E19082-01/819-2723/disksconcepts-20068/index.html),
so it will overlap any other slice.

zpool is correct in warning you about this, but in many cases you might
just want to use the entire disk ('c15t0d0' should work). I'm not sure
whether you can do that with rpool disks though, since they need to boot
from somewhere.
