Answer
 
By having multiple contexts you can utilize the 'multipass' 
sql feature. Multipass: Breaking one large SQL into 
multiple SQLs.If you are using the star schema with two or 
more fact tables,and you enable this feature, BO will 
automatically generate two or more SQLs (i.e. one SQL for 
each fact table object used in the report). Then the 
results will be synchronised in the report. For more on 
multipass concept please refer to Ralph Kimball's Lifecycle 
toolkit (not modelling)book.
