Name-based virtualhosts and SSL wil only work if all the virtualhosts are within the same domain and you have a wildcard SSL certificate for that domain.
But you have 2 different domains.
In this case it will only work if you give each SSL-enabled virtualhost it's own IPaddress. So you should use IP-based virtualhosts, not Name-based.
Explanation: The ServerName which is requested, is contained in the HTTP request headers, but before that the SSL encryption must be already setup. So the ServerName is only available after the encryption has been setup. Therefore Apache can never know which SSL certificate te serve up and wil just use the first one available on that particular IPaddress.
