Not able to do FULL uninstall from multisite network

Hello, I am running a multisite network and installed woocommerce from network admin. Hit the network activate button and created some test products and played with plugin. I tried to uninstall following this guide http://docs.woothemes.com/document/installing-uninstalling-woocommerce/. I checked Remove Post types on uninstall and hit delete. After re-installing plugin, test products were still there so it looks like “Remove Post Types on uninstall” didnt work. Is there anything I can do about it?
