They stay on. The rear sidelights are low wattage compared with the headlights, so there would be no advantage in dowsing them to aid starting.
(The same as the front sidelights)
One difference between the Volvo and more modern DRL systems is that the rear sidelights are always on when the ignition is on, as are the 10% headlight DRLs. So a Volvo in motion in poor daylight with no lights deliberately turned on is nonetheless illuminated front and rear.
A modern car may have over-bright illumination from its lights that look like foglights, but still show no lights at the rear. The point of course of proper DRLs like the Volvo is to be visible to others. The existence of bright lights to the front often seems to cause drivers to forget about the need to be visible from behind.
