Difference between Comma and Asterisk

Question

Can someone please explain to me the difference between the following queries

SELECT
    NON EMPTY {([Measures].[MeasureName])} ON COLUMNS,
    NON EMPTY
    {(
    	[Dimension01].[ColumnName01].AllMembers
    	* [Dimension02].[ColumnName03].AllMembers
    	* [Time Period].[WeekStartDate].AllMembers
    )} 
    DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
FROM [CubeName]

and now using commas

SELECT
    NON EMPTY {([Measures].[MeasureName])} ON COLUMNS,
    NON EMPTY
    {(
    	[Dimension01].[ColumnName01].AllMembers,
    	[Dimension02].[ColumnName03].AllMembers,
    	[Time Period].[WeekStartDate].AllMembers
    )} 
    DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
FROM [CubeName]

I really don't know anything about MDX, but I'm gonna venture a guess that the asterisk is the multiplication operator and the comma defines 3 different columns. Again, just a guess although BOL does state that the asterisk is the multiplication operator.
