question about property value cardinality

Here is a citation from the notes of 
the Apr 28 meeting:

  

  
Q: (Fred) Is the resource properties value 
  multi-valued

  
A: 
  No.

I don't understand this answer.  
If the properties are only allowed to be single valued, the simple Get/Put 
operations would be sufficient.  But WS-RP includes  
Get/Update/Insert/Delete  operations.  This implied to me multiple 
values, otherwise Update and Insert are only minimally different.

 

Can someone clarify why there are all 
four operations for single valued properties?
