Use case of adding {last_segment_category_url_title}

gistfile1.txt

<!-- Using @litzinger URL Helper plugin I added a new variable: 

{last_segment_category_url_title}

This parses only if the last segment is a valid category  (see case 3). I need this variable b/c {segment_3} will always parse, thus the third case returns true every time.

{all_segments} is perfect for the switchee variable b/c it's dynamic rather than hard coded: {segment_1}/{segment_2}/{segment_3}/{segment_4}

ie. 
/products/
/products/cat
/products/cat/entry
/products/cat/subcat
/products/cat/subcat/entry

{exp:switchee variable="{all_segments}" parse="inward"} 

{case value="{segment_1}"}
	<!-- if s1 is products and s2 is empty, show product home -->
	{embed="products/_home"}
{/case}

{case value="{segment_1}/{segment_2}"}
	<!-- if s2 is present, show category - all single products are either s3 or s4 -->
	{embed="products/_cat" page_type="parent"}
{/case}

{case value="{segment_1}/{segment_2}/{last_segment_category_url_title}"}
	<!-- if s3 is present and is a category -->
	{embed="products/_cat" page_type="child"} 
{/case}

{case default="yes"}
	<!-- if s3 is an entry or s4 present, show single entry -->
	{embed="products/_single"} 
{/case}
