It does matter.
For example, I have
Profile WHERE Profile.Category=A
and
Profile WHERE Profile.Category=B
When I run process
Find Profile WHERE (Profile.Category="one of" NonPersistedObject.Category)
WHERE NonPersistedObject.Category contains category A and B
I want to see in the result both Profiles but not one:
Profile WHERE Profile.Category=A
and
Profile WHERE Profile.Category=B
