[PF] Making better use of the Bleeding condition

[Hallack]

Bleed

A creature that is taking bleed damage takes the listed amount of damage at the beginning of its turn. Bleeding can be stopped by a DC 15 Heal check or through the application of any spell that cures hit point damage (even if the bleed is ability damage). Some bleed effects cause ability damage or even ability drain. Bleed effects do not stack with each other unless they deal different kinds of damage. When two or more bleed effects deal the same kind of damage, take the worse effect. In this case, ability drain is worse than ability damage.

So, as per the highlighted portion of the bleed condition you can stack bleeding, such as from the Bleeding Attack rogue trick so long as you are using weapons that cause different types of damage.  Use a slashing weapon and a piercing weapon for example.

According to the example you listed, it seems to indicate that "different kinds of damage" mean damage to different things. it treats ability drain and ability damage as the "same kind" (Stat Damage), which would put slashing/piercing/bludgeoning under one kind (HP damage)

Drat, I think you are right.
