Can ProSites users have multiple sites subscriptions?

Hi, I am using ProSites for my multisite install. I have some questions about the plugin...

1) If a user finished Site1 trial perdiod and is now paying for Site1, then goes and creates Site2, does Site2 have the trial period as well?

I performed this test and did not see the days left dashboard notification on Site2.

2) If Site2 runs out of trial period before the user pays, does it lock down? (if that setting is enabled)

3) If the user pays for Site2, do the payments charge separately or they are combined (if the user is paying for Site1 and Site2)
