MDX: Performance Question

Hi,
In terms of performance, is there a significant difference between:
With [MySet] as '[Customers].Members'
Select {[Measures].[Unit Sales]} on Columns,
Union(
CrossJoin([MySet], {[Dimension].[MyMember]} ,
CrossJoin([MySet], {[Dimension].[MyOtherMember]}
)
on Rows ...
AND
With [MySet] as '[Customers].Members'
Select {[Measures].[Unit Sales]} on Columns,
CrossJoin([MySet], {[Dimension].[MyMember], [Dimension]
.[MyOtherMember]}) on
Rows ...
?
Thanks in advanceNo, there shouldn't be.
