No, it makes perfect sense once you get it.  Why should the for-each
care whether you select 1 node or 1000?... you are still doing
something "for each" node selected.

Switching variables is a different matter, eg

<xsl:for-each select="$someVar">
  do something
  <xsl:for-each select="$someOtherVar">
    do something else

"for-each" doesn't really fit there, so maybe there's scope for
something there... but usually when I find something in XSLT that I
don't think is quite right, after using it a few times (and perhaps
after a few posts to xsl-list) I realise I was wrong and the design of
XSLT is in fact, genious :)
