from what i understand , google handles 302 this way because of doorway pages.

If index is a doorway then pagerank goes to index from the content it points to. At least thats how it's supposed to work.

This was found out and exploited by hijackers in 2001 and is now called 'googlejacking'
Google thought they could take the 'wait and see' approach and the 'spammers will cause their own downfall' approach.
I seriously thought the Alegra update would deal with this but apparently not.
The reason google handles 302's this way is to deal with the way the web was built (doorway pages) when they came on the scene.
Today the web is being built around googles policies. Maybe it's time to penalize doorway pages.
Sure you will be penalizing a lot of legitamate web pages but you can bet that if google did this, doorway pages would be a thing of the past right quick. At least webmasters would have control of their own destiny.
After all doorway pages used to handle by HTML what scripts could easily do today.
also for pages that are depecrated they could come up with a self-depecrating tag rather than a redirect that steals the fire from the previous location.
Hijackers could never exploit a self-depecrating statement.
