I went there recently and confirmed that it is chevrons, not double white lines, and afaik chevrons cannot be crossed even for turning right.

Interestingly, the chevrons start a bit after the kerb (you can kind of see this on aerial imagery). I can't tell if this is done deliberately to allow vehicles to turn right from Kiu Hing Road, or if the paint has simply worn out from heavy vehicle turning. Anyhow, Kiu Hing Road has right turn arrow, so we don't have to worry about that.
