PEX - '*' doesn't give all permissions?

I'm using the plugin EchoPet and there is multiple permission associated with it... Why is it that giving my Owner group the permission - '*' doesn't actually give permission to all of the commands?
Here's what my group did look like: http://pastie.org/8654438
But that still didn't give me access to the command /pet remove . The permission needed to use that command is echopet.pet.remove so I added

Code:

- echopet.*
- echopet.*.*
- echopet.pet.*

and still, I didn't have permission to use the command until I actually added

Code:

- echopet.pet.remove

.... Why?
Why isn't - '*' good enough?

 

AdamN Some plugins just don't support the - '*' wildcard. Because of this, it's always important to check your plugin's documentation pages to see which permission nodes you may or may not need to add.

 

When using PEX, '*' grants EVERY node. Even the nodes that plugin authors specifically labeled as not for OPs.

 

mbaxter Alrighty, then I'll let you give an explanation to AdamN for why he doesn't have permission to use the commands until he added the specific nodes. I know '*' is supposed to give everything, but in my experience, sometimes it doesn't. Apparently my experience is wrong.
