Yeah, Ive heard similar things. If you are too gentle with the running in you can polish the bore too much rather than 'wear' it in which will in turn make the bike burn oil. As Dazmatic says it IS the pressure building up on the rings that makes them seat against the bore maintaining a seal.
Soooooooooo many theories, but than as JMo says if you do it as per the manual you do have comeback if the engine fails at a later date.
On my first Tenere I did as the manual for the first 600 miles before the first service and thereafter when I was sure that it was up to working temperature I used to ride it as I intended and it seemed just fine.
