I think this is because of the shutter settings Razer has used with the 2013. If that is the case, when you place the mouse back down move it a short distance quickly, that should "wake" the mouse up faster. This is something I seen done with wireless/laptop mice. I think their reasoning for doing it is to help with lifting and repositioning / LOD. They may have added to much delay to be acceptable for gaming.
What Wevsspot said is also an indicator of this. In wireless mice (Logitech) if you place something near the sensor/LED, that may or may not cover the lens, will keep the mouse "awake" longer or all the time.
Maybe the Razer software can change this behavior with their "calibration" settings.
I had the same idea... However, when playing with a mouse like that, the amount of movement necessary to wake the mouse was to much for gaming. You have to change your play style to work with this behavior. Which in this case is counter to what most are used to -- having to always move your mouse to keep it working...
I guess this is a side effect of users complaining about the older DeathAdder's LOD. I assume, they don't want to sacrifice performance, so they tried this route out.
