Because it's correct!
The {./@color} is an attribute value template, the thing between the curly
braces is an XPath expression which is substituted into the attribute value
at the relevant place.

But don't try this construct anywhere, there are only certain places it can
be used.

Your variable here will be out of scope as soon as you hit the </xsl:if>

You can use variables, but you haven't said what you want to achieve with
them so it's difficult to advise.
