The xsl:variable here is redundant as the variable is never referred to; and
the xsl:element is producing an element that doesn't depend in any way on
the content of the current group.

For an example of how to use group-starting-with, see 

http://www.w3.org/TR/xslt20/#grouping-examples

specifically, the example " Identifying a Group by its Initial Element "
