I just tested SSL logins with the JA_Purity theme and it works (though I never checked the logs) Logically, there shouldn't be any behavioural/functional differences depending on theme selected.
I can confirm that when logging in via SSL, the connection remains in SSL. I don't think this is a bug but rather intentional. If you would like to change this behaviour, I would recommend asking the joomla guys. UPDATE: I just found your post on the joomla forums, if/when you solve this issue, drop us a line as others might also be interested.

BTW, thanks for the "TurnKey rocks!" mention :)
