I don't think posting their SEC filings on their own website has any significance. There's no obligation for them to do so, since SEC publishes all that stuff on EDGAR. They probably have a few people working while in BK, and they periodically update the easy stuff (probably just to stay busy so they can justify getting paid!). Perhaps the lawyers wanted an all or none situation: either take all the SEC filings down, or make sure they are all there, so, it was probably easier just to add a few, than remove the entire investor relations/sec filings links. Just guessing, of course! who knows!
