Multiple Parents / Does not show child term in URL Alias

Essentially the taxonomy tree that I have created is:

Vocabulary
A
-1
B
-1

In the example above I have terms A and B set to both be the parent term of the child -1 using multiple hierarchy. Multi-select is enabled. I have a CCK node with a field for the content taxonomity. I have multi-select enabled on the CCK field and check off both terms in the node upon save. The pattern for the node path is set as [vocab-raw]/[termpath-raw]/[title-raw]. I need the output to be Vocabulary/A/-1/title. My output though is Vocabulary/A/title. Is this a bug or am I not doing something correctly?

Thanks in advance for your help.
