Did you define BP_ENABLE_MULTIBLOG in your wp-config.php?

If you want to run BP on all of the sites/blogs in your network, that’s done with the constant above. That isn’t what my patch was for. Secondly, my patch only provides hooks for a plugin to implement social network segregation. With just my patch applied BP should continue to work the way it did without the patch.
