It's intentional and the reason for it is that people voted for it, but I can't read their minds to tell you why they did so.
It can be quite convenient though when writing a micro-pipeline:
<xsl:variable name="selected-nodes" select="...."/> <xsl:variable name="selected-nodes" select="if (XYZ) then $selected-nodes else ...."/> <xsl:variable name="selected-nodes" select="if (PQR) then $selected-nodes else ...."/>
Hmmm the convenience of not having to use distinct variable names versus a few hours debugging (followed by raw anger that you really did make that mistake)....
At least its reasonably well known it seems. It came as a surprise to me as it doesn't feel right for XSLT, which is usually more strict.
