When the US Core tests check for the presence of a Must Support element within a slice, they check for an element at that path anywhere in the resource, rather than only within that particular slice.
In the US Core Blood Pressure Profile for example, if a resource contains component.valueQuantity.value, that would satisfy the Must Support requirement for component:diastolic.valueQuantity.value and component:systolic.valueQuantity.value even though that field may not actually be in either slice.
