Constrain on empty variable in microflow retrieve

3
Just wondering, if a Microflow retrieve activity retrieves objects with a constraint such as [MyAssociation = $AnotherObject] and $AnotherObject = empty. Does it throw an exception or does it return all items where MyAssociation is not set?

Figured it out myself, the answer is neither of them:

The result set is just always empty when $AnotherObject does not resolve.

(When MyAssociation is a reference, did not test for references)
