SunOS sparc sed users

I'm trying to locate a bug in sparc/Sun sed, running SunOS version 
5.9. I'm getting this problem:

******BEGIN COPIED OUTPUT******
  gmurik@Zapata:        /idn/dm/home/gmurik/unix/sed> uname -a
SunOS splma503 5.9 Generic_118558-11 sun4u sparc SUNW,Netra-T12
gmurik@Zapata:        /idn/dm/home/gmurik/unix/sed> cat 6lines

gmurik@Zapata:        /idn/dm/home/gmurik/unix/sed> wc -l 6lines
       6 6lines
gmurik@Zapata:        /idn/dm/home/gmurik/unix/sed> sed -e '$!{h;d;};x' 6lines
last

******END COPIED OUTPUT********

By my way of thinking (and after trying it out here several times), 
the output of

     sed -e '$!{h;d;};x' 6lines

should have been "2nd" instead of "last". I cannot diagnose what is 
wrongly happening here. I've tried working with several other 
versions of sed (gsed, ssed, csed, sed16, etc., including sedsed) and 
I cannot figure out what's wrong here. That little script OUGHT to 
print the 2nd to the last line, not the last line! Is it a bug in the 
SunOS sed?

Can any Sun users help me out?
