Reason it probably worked as you expected is because you
probably had two templates like:
match="paragraph"
and
match="paragraph[position() = 1]"

There's a priority scheme for templates which is fairly well
documented in most places where you'd look up template matching
stuff.  Some of the pieces of information which I personally
found most useful:
a) stuff with [] predicates get higher priority 
b) using a '|' doesn't increase priority in and of itself

You can override this priority directly, but I've been burned
a few times in doing that.. generally if I have something which 
I very specifically want called, I'll use a call-template, or
perhaps a mode.

Normally, the calculated priority works well.. and I guess if
I kept the actual values related those calculations in mind
while programming, it might make using priorities more
effective.

Hope this helps.
