Actually, you should *not* expect the above.   See

This holds for all functions, not just unpack.  If the function 
invocation appears anywhere in the list of arguments to a function, 
except the last position, its list of return values is adjusted to 
return just the first value.

If it wasn't midnight, I could probably explain this more clearly.
