I have heard this too - and follow it as much as I can by tanking up at 1/4th itself. The logic is that the fuel pump is a highly stressed component, what with having to pump fuel into the common rail which itself is under several bars of pressure. So enough fuel in the tank helps. Also, having more fuel implies less impurities per volume, and less moisture presence - both can be killers of the CRDi.

If you want your diesel engine to last long, work the torque and upshift early. No point in high revving common-rail diesels; their redline starts way too early (4,000 rpms or lower, compared to 6,000 for most petrols). All the torque is lower down the rpm range anyways.
