Looks like it's just been divided into ~1.3Vs, "slow", "stupidly slow", and "you've stalled you idiot".
That is looking at it with a 1 'g' airline mentality. The word 'slow' is a misnomer. The airspeed is likely quite OK for flight.
This is an aircraft that is maneuvered aggressively.
Stay out of the Red zone and you are flying.
If you pull it into the red zone and it begins to depart, push it forward until you are out of the red zone.
The cross hatch area tells you that you had better have this gage in your scan and to pull smoothly to avoid nasty surprises while maneuvering.
