I cannot see how this might be true in any situation except when your core product and efforts are always in one particular direction and a very particular area.

Many companies shift focus -- partially or completely -- as they grow, so I cannot see the wins in the quoted approach. You might gain a perfect understanding of an area and how a feedback loop improves productivity there but is that such an universal wisdom that it applies everywhere else you might go in the future?
