To be bloodied, you must have triggered the Bloodied Value state, to be dying you must have triggered the dying state. The states happen one after the other.
While I'm no fan of Regicide's, I'll note that 'exception based design' is one of the most misused phrases in debates about the rules. People consistently fail to understand what it actually means.
I noticed under the Level 22 Cleric power Revive the Target is:
Target: One bloodied or dying ally or a dead ally who died during this encounter
It seems odd to me that if Dying implies bloodied then why would it be called out specifically here. If you are Bloodied while you are Dying then this would be redundant. So it seems that this implies they are exclusive...so when you become Dying you cease to be Bloodied.
The same verbage appear in the Darksun Power Wings of Gold under the Effect:
...Any bloodied or dying ally that starts his or her turn within the zone regains 10 hit points.
It seems that is Consecrated Ground was meant to work on Dying allies it would be in the effect of the power as such.
