AFAICT they are used in different stages of the designing cycle. The 
untyped association indicates that there is a functional one to many 
relationship between objects, and later you may go over the objects 
life-time cycles and dependencies, and turn that one-to-many 
relationship into an aggregation or compisition (which is closer to the 
actual implementation of the relation).

Later on, code generation may give you options as how to implement these 
aggregations (as data members, as managed-pointers, as foreign 
reference, etc.)
