with https, SSL negotiation occurs before any http. this means you *must* have a seperate IP address per https site, and *any* https connection to the address you're using will be negotiated against the proorthapedic certificate.
look at it this way - http and https are entirely different servers that just happen to be serving the same content. with http you can share multiple sites on a single IP address, but with https this is impossible. the only way to fix your problem is to shift the https enabled site off to it's own IP.
