I'd just like to make sure that I'm reading this correctly
This only pertains to the older powdered formula hemocoagulants and not the newer inpregnated dressings right?
Correct, but technically the specific powders that were phased out were the old formula of QuickClot and WoundStat.
It should be noted that Celox was never used by the military in it's powered form, at least not service wide (some units may have used it) and Celox has not been linked to any of the complications of the QuickClot or Woundstat.
From a practical point of view, the powders are a poor choice for most applications vs. the impregnated dressings.
