Have a question on dispatcher statfileslevel

I am configuring dispatcher and doing some tests. I have set the statfileslevel as 7.

When I activate /content/we-retail/language-masters/en/products/women/shorts/candide-trail-short.html, the dispatcher touches all the stat files in content, we-retail, language-masters, en, products, women, shorts

Then I have accessed /content/we-retail/language-masters/en/products/men.html and men.html file in docroot was invalidated and pulled from publish server

When I accessed /content/we-retail/language-masters/en/products/men/coats/slopeside-coat.html, the cache is not invalidated and served from cache due to the fact that stat level is 7 and the statfile in /content/we-retail/language-masters/en/products/men/coats is not touched due to activation of /content/we-retail/language-masters/en/products/women/shorts/candide-trail-short

My question is why men.html is invalidated though it is not related to any content on /content/we-retail/language-masters/en/products/women/shorts/candide-trail-short and can we avoid this?

As these would be the highly viewed pages on the site, I want to avoid their invalidation when other page in the hierarchy is activated,
