Can Anyone Explain?

Seriously, can anyone explain to me what this story is about?

Obama clears way for oil drilling off US coasts

Reversing a ban on oil drilling off most U.S. shores, President Barack Obama on Wednesday announced an expansive new policy that could put new oil and natural gas platforms in waters along the southern Atlantic coastline, the eastern Gulf of Mexico and part of Alaska...

The plan modifies a ban that for more than 20 years has limited drilling along coastal areas other than the Gulf of Mexico. It allows new oil drilling off Virginia's shoreline and considers it for a large chunk of the Atlantic seaboard...

In addition, the Interior Department has prepared a plan to add drilling platforms in the eastern Gulf of Mexico if Congress allows that moratorium to expire. Lawmakers in 2008 allowed a similar moratorium to expire; at the time President George W. Bush lifted the ban, which opened the door to Obama's change in policy...

At the same time, the president also announced that proposed leases in Alaska's Bristol Bay would be canceled. And the Interior Department is reversing last year's decision to open up parts of the Chukchi and Beaufort seas. Instead, scientists would study the sites to see if they're suitable to future leases...

I am 100% serious here...can anyone with decent knowledge of the topic explain this to the rest of us? What I see is a story about 'Obama lifting a ban on offshore fossil fuel exploration'. But then I see that Bush lifted the ban in 2008. And then I see that in at least one location Obama is actually enacting a ban. Am I missing something? I must be, but I'm not seeing what or where it could be.
