The brain is not symmetrical, so a normal template should not be either.
Actually, if you display the template and go to the y=13 plane, you can
clearly see the asymmetry in the occipital lobe, where it is usually
most pronounced.

The convention in spm for some time now has been that it will try to
show images in neurological convention, i.e., left is left. This is
actually not as trivial as it sounds (try searching the archives for
mails by "John Ashburner" including the term "left", which will give you
some material to delve in further into the handedness of coordinate
systems :)
Cheers,
Marko
