Wouldn't a simpler option be to use "current()" rather than "."

<xsl:template match="/">
       <xsl:variable name="tokens" select="tokenize('foo bar bat', '
       <xsl:for-each select="1 to count($tokens)">
           <token index="{.}">
               <xsl:value-of select="$tokens[current()]"/>

Agreed, I don't see a difference either.

Because the predicate opens a new, inner context. The XPath
recommendation (http://www.w3.org/TR/xpath20/#dt-context-item)
explains it as follows:

  "Certain language constructs, notably the path expression
  E1/E2 and the predicate E1[E2], create a new focus for the
  evaluation of a sub-expression. In these constructs, E2 is
  evaluated once for each item in the sequence that results
  from evaluating E1. Each time E2 is evaluated, it is
  evaluated with a different focus. The focus for evaluating
  E2 is referred to below as the inner focus, while the focus
  for evaluating E1 is referred to as the outer focus. The
  inner focus exists only while E2 is being evaluated. When
  this evaluation is complete, evaluation of the containing
  expression continues with its original focus unchanged."
