2 and 70
You are mixing autothrottle modes with pitch modes. Autothrottle has a mode window but no flightdirector indications. The only flightdirector associated with speed only is the Lvl chg mode, where the throttles during desent are at idle and speed is maintained by changes in aircraft pitch.
You can manually fly the 73 using flightdirectors, with autothrottle engaged, deselected or switched off completely. You may fly with flightdirectors on either side or both.
