I’m new to DAX and still trying to get the hang of the basics!

I’m trying to get a distinct count based on whether a filter matches multiple values on the same column.

eg. based on the following dataset

PersonId     Col1
1            -1
1            10
2            -1
3            100
4            100
5            -1
5            30
6            -1
6            100

I want a distinct count where a PersonId has a row with -1 AND another row that isn’t 100 for Col1.

So that would be PersonId 1 and PersonId 5. Total 2.

This is the Dax I’ve got so far and it’s not giving me the correct results. Returning 4 instead of 2.

_Measure = 
    CALCULATE (
        DISTINCTCOUNT('Data'[PersonId]),
        Data[Col1] IN { -1, 10, 40, 60, 90 } 
    )
