How is it that i am getting two different open ids for the same site for the same user

I was under the impression that the open id for a user remains constant.

I am allowing users to setup open id with my site with 2 different screens in my app...

I was under the impression that the open id for a user is constant and will not change and I was planning to save it to my database for a given user,

However, to my suprise, I found different ids for the same user using the same google account in the two different screens.

How does open id actually work ?

Update: I found that google does so based on open ID realm. so for the same realm, two open ids will be same (irrespective of the url parameters)

You've already found the answer to your question then: Google uses "directed identity", meaning the openid.realm determines the scope that an openid.claimed_id applies to. If you want both "screens" to get the same OpenID, make sure the realm is the same, perhaps by simplying it down to http://*.mydomain.com/, including the wildcard character.
