Pivotting unpivotted data in Power Query

Why can't I have the same number of records after pivotting unpivotted data in Power Query? Am I missing something?


Table.Pivot( Table.FromRecords({ [key = "x", attribute = "a", value = "r1"], [key = "x", attribute = "c", value = "r1"], [key = "x", attribute = "c", value = "r2"], [key = "y", attribute = "a", value = "r1"], [key = "y", attribute = "b", value = "r1"] }), {"a", "b", "c"}, "attribute", "value", List.Max <- aggregation function )

In this case, if I don't select to aggregate the data by any function available (Count, Count Distinct, Min, Max, Median) I get an error because "attribute = c" for "key = x" has multiple values associated with it. Wouldn't it be better to have those multiple values spread into distinct rows instead?
