Malgus lifted his own blade slightly towards his own face as something of a salute. Not really in a mocking fashion as he did to goad the Jedi at the temple though.

While his own posture was not defensive, it wasn't aggressive either. He waited a few moments to see if the Jedi would attack first.

When he didn't move, Malgus went to make the first strike. He leaped forward with speed aided by the Force and intent to slash at Ben's midsection.
