This is exactly what our "Master Intensity" also does, but it's not 
connected to a cue, but to a bunch of channels (most of the time the 
same channels as you are using in cues for this group).

In our case the submaster keeps in charge, also for next cue, so 
effectively you reduce (or increase) all light channels (no, all 
Intensity channels) of this group of channels.

Are submasters really working during one cue only?

That is our group Intensity wheel, but that is different from the 
Master Intensity. We used to call the Master Intensity "Gain", as it 
far more clear what it does, but that term is unknown in the lighting 
world :-)  Still, it's gain as all DMX values are multiplied by this 
factor, so 0.5 is effectively 50% of the original value.
