Why Did the Times Switch This Solyndra-Program Headline?

When Neela Banerjee's summary of a Department of Energy audit went up on the Los Angeles Times site at two minutes after noon on the west coast, it seemed to imply that Energy Secretary Steven Chu had a less-than-sure hand on the DOE's green loan guarantee program: 

Then, maybe sometime before three minutes after noon, the same story shed its headline and grew a new one, which retroactively manages expectations of how damaging the audit was going to be: 

In my day a switch like that might have been necessitated by another story competing for paper real estate, or to avoid butting headlines, or due to the cancelation or addition of an advertisement. I don't miss those days, but sometimes I miss the non-malleability of paper and ink.

I don't imagine such scarcities apply at a news web site, but I did hear a while back that the FCC is in charge of the internet now. So there's that. 

Otherwise, why did this headline change?
