Because visibility.

You're basing quite a lot on a grainy photo-shop edited photo with lots of photo artifacts, and without any context.
Here's a little more info.

Apparently the driver was on a hand held cell phone (or similar) at the time of the impact. And, apparently there is no evidence of him taking evasive action.
The riders are to the right, but not hugging the guardrail. Reports indicate the rear rider had a flashing light, and they all had "visible clothing". From the photos provided, they appear to be visible as the bus is approacing.
I'm not convinced the outcome would have been any better had the riders been more central on the road, except possibly being missed by the tires if they were lucky.
Mirrors might have influenced a decision to bail off the road.
