An applicability test should be run once and if a match is found, all recipes in the list should be run.
So if one of the recipes in the list makes a change which would cause the applicability test to no longer match,
subsequent recipes in the list should still execute.

If the applicability test is incorrectly applied to individual recipes in the list, the (incorrect) result would be "2".
