SSL over http instead of https

Hi list,
I recently reviewed a web hosting provider, and made the assumption that due
to them not having https that they were not running SSL on their login
screens- therefore exposing credentials in cleartext.
However after reviewing the packets it became apparent that when you entered
the credentials, there was in fact a ssl handshake and the data was in fact
encrypted via sslv3.
Is there any logical reasoning for this- it would appear they use a IIS
webserver for this purpose.

Cheers
