Bad Editing, Or An Attempt At Humor?



JPL's recent press release mentions the evidence that the area the Rovers are exploring was not only wet once, but wet twice--which might explain why the press release is a bit repetitive:

About six months ago, Opportunity established that its exploration area was wet a long time ago. The area was wet before it dried and eroded into a wide plain. The team's new findings suggest some rocks there may have gotten wet a second time, after an impact excavated a stadium sized crater.



By six months ago, Opportunity had established that the area it is exploring was soaking wet long ago, before it dried and eroded into a wide plain. New findings raise the possibility that some rocks there may also have gotten wet a second time, after an impact excavated a stadium-sized crater in the plain.

Or are they worried that many people need to be told the news twice, to make sure it sinks in?
