The online notification system can be confusing at times--who knows whether that is due to data entry errors or whether it is technical. In any case, what happened here is that the case was likely denied, then the case was reopened. This means that for the moment the case is nether denied nor approved, but still pending--as if you never got the first email at all. With respect to H-1B extensions, a three year extension is possible if the I-140 is approved. You also may be able to recapture time spent outside of the U.S., if applicable. You can discuss this as well as other nonimmigrant visa options (E-2, F-1), if applicable, with an immigration attorney.

It sounds like someone filed a motion to reopen (MTR) the denial; reopening means that the denial is being reconsidered and may be reversed. Perhaps it was your employer's lawyer who filed the MTR. You should talk to him.
