Given

• bug_a tracker with stage list field with a static binding with: Todo, On going, Done
• bug_b tracker with stage list field with a static binding with: To Do, On going, Done
• bug_a 1 whose stage value is Todo
• bug_b 2 whose stage value is To Do

SELECT @pretty_title
FROM @tracker.name IN('bug_a', 'bug_b')
WHERE stage IN ("Todo")

Should return bug_a 1

SELECT @pretty_title
FROM @tracker.name IN("bug_a", "bug_b")
WHERE stage IN ("Todo", "To Do")

Should return bug_a 1 and bug_b 1

As of 16.4.99.151 the second query triggers an error "Error while fetching the artifacts matching the query: The value 'Todo' doesn't exist for the list field 'stage'."
