What does Min/Max aggregation mode return when using interval samples?

The user manual indicates that Min/Max returns 2 values (min&max) for the sample window, but when using interval mode, it only returns 1 sample per interval window, and it appears to return the same value when using closest value, minimum, or maximum. In interval mode, is Min/Max basically the same as closest value? Not an issue if that’s the case, just wanted to know.
