Err... no idea.  I tried the following in Saxon 5.5.1:

--- XML File ---
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>
<doc>
   <item>Item1</item>
   <item>Item2</item>
   <item>Item3</item>
   <item>Item4</item>
   <item>Item5</item>
</doc>
---

--- Stylesheet ---
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output indent="yes" />

<xsl:variable name="maxItemsPage" select="3" />

<xsl:template match="/">
   <xsl:apply-templates select="//item[(position() mod $maxItemsPage) = 1]" />
</xsl:template>

<xsl:template match="item">
   <group>
      <xsl:for-each select=". | following::item[position() &lt; $maxItemsPage]">
         <item><xsl:value-of select="." /></item>
      </xsl:for-each>
   </group>
</xsl:template>

</xsl:stylesheet>
---

and got, as expected:

--- Result ---
<?xml version="1.0" encoding="utf-8"?>
<group>
   <item>Item1</item>
   <item>Item2</item>
   <item>Item3</item>
</group>
<group>
   <item>Item4</item>
   <item>Item5</item>
</group>

So *perhaps* it's the processor - you could try out the above to see
what you get - or perhaps it's something about the context in which
you're using the expression, or perhaps I've overlooked something
somewhere.  Feel free to send me your stylesheet if it's bothering
you, although as you've found a way that works I'd just stick with
that if I were you ;)

I hope that helps,

Jeni
