Note, that the connection to the megaupload case is 100% based on speculation by the Paidcontent author (unless he was tipped to the existence of the documents in the docket.. he doesn't say how he stumbled across them).
What we do know for sure is that Google received a 2703(d) order (for non-content and subscriber info) and a search warrant (which could reveal communications content). Google later asked the court to unseal the orders.
I'm not sure why the government would seek both a d order and a search warrant for the same account (since a warrant also allows you to get everything that a d order delivers).
One possible option might be that the warrant (probable cause standard) was for one particular target for which the gov had more evidence, whereas the d order was used for other targets in the same investigation for which the government could only meet the "relevance to an ongoing criminal investigation" standard.
