That doesn't look wrong to me. <xsl:value-of select="false()"/> will create
a text node whose string value is "false", just as if you wrote
<xsl:text>false</xsl:text>.
Moreover, <xsl:when test="not($samePath)"> is definitely wrong. $samePath is
a result tree fragment, and converting a result tree fragment to a boolean
should always give true.
Looking at the logic, why not make $samePath a boolean variable? This is
possible even in XSLT 1.0:
<xsl:variable name="samePath" select="$to=$from and
not(contains(substring-after(substring-after($to,$from),'/'),'/'))"/>.
Replaces 20 lines of code by one, and if you can do that a few times then
more of us might be inclined to look at the code and help you with it.
In fact that immediately seems to show a flaw: if $to=$from and both are
strings, then substring-after($to, $from) is "", and substring-after("",
"/") is "", and contains("", "/") is false, so the condition reduces further
to:
<xsl:variable name="samePath" select="$to=$from"/>
