JBII uses an outside accounting firm as well as their auditor's review for their 10Qs. If they file a routine extension again that they've been doing every quarter for a while now, then most likely it's because their outside firm is still reviewing the 10Q. At the AGM John said they're not going to make extra expense to get the filings out earlier and would rather use the money toward building P2O, but the filings will indeed all be done.
As for what filing a 5 day extension means? I've said this before, and I'll say this again -- the very last time with another company I owned there was a heated debate on what that means the penny stock, ironically, got bought out in an all cash buyout for a massive premium shortly after the debate proving that the NT was meaningless.
