That's not quite true. It assigns a single text node containing '1' to
the variable.
But as the test is a scalar test it compares the node after doing a
normalize-space on it
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:variable name="mode1" select="'1'" />
<xsl:variable name="mode2">1</xsl:variable>
<xsl:template match="/">
<html>
<body>
<xsl:if test="$mode1='1'">Mode 1 =
'1'</xsl:if>
<xsl:if test="$mode2='1'">Mode 2 =
'1'</xsl:if>
<xsl:if test="$mode2=$mode1">Mode 2 =
Mode 1</xsl:if>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

That isn't the case. It is not declared at the top level it is declared
in the template that matches "/". Declaring it at the top level means
declaring it at the top level of the stylesheet as I have done above.
If you want to do different things depending on mode you probably want
to have a mode attribute on the template
<xsl:template match="/">
<xsl:apply-templates select="some_thing" mode="mode1" />
<xsl:apply-templates select="some_thing" mode="mode2" />
</xsl:template>
<xsl:template match="some_thing" mode="mode1">
... Do something with some_thing for mode 1
</xsl:template>
<xsl:template match="some_thing" mode="mode2">
... Do something with some_thing for mode 2
</xsl:template>
