I am confusing the follow logic:

AND: "Occurrence A of Encounter, Performed: Encounter Inpatient (facility location arrival datetime, facility location: 'Hospital Measures-Non-ICU Locations')" starts before start of "Occurrence A of Encounter, Performed: Encounter Inpatient (facility location arrival datetime, facility location: 'Hospital Measures-ICU Locations')"

Does it mean one encounter may have two facility locations or the occurrence of the second encounter must be B (not A) ?

Because the generated data from Cypress does not have any of this case, so It makes me confused.

Please give me advice

Thanks
