Correct, and since the starlink satellites are in Low Earth orbit the period of time you, the observer, have dark skies, and the satellites above you are being illuminated by direct sunlight can quite short.
Over the months I've found the trains
aren't always that easy spot, even from a dark sky site, so I wouldn't be at all surprised if one got missed from a light polluted area.
BTW I've used the Heavens Above site for years, I know the the interface isn't perhaps that fancy but it works.
