Question for PGOOD pin

Category: Datasheet/Specs
Product Number: LTC3290

Our  customer have questions for LTC3290 PGOOD question, 

Dtasheet said"Power Good Output. This open drain output is low when the part is enabled and the output is not in regulation. Once the part reaches regulation, this pin transitions to a Hi-Z state."

when EN Pin is high, Vout failing or meet other problem, how about PGood PIN change?

I guess we test curcit as below shown, Pgood is high when output reaches regulation and Pgood is low when utput meet some problem?

it is right?
