The idea of a fast break-in/fast car later has been around for YEARS. What is comes down to is that in a fast break-in, at least in years past, you would actually cause the engine to become "looser" (re the bearing/piston clearances)and thereby have less internal friction. That, of course, would result in a slightly more responsive engine, for a while. Since you have, in escence partially worn the engine out by doing this, you often ended up driving an oil burning mess when the miles built up. This is another matter in which you pay your money and take your choice. I, personally, hope my Odyssey never wears to that point and, with a nice proper break-in and with Mobil-1, it could happen.
