All that means is that it will run a 32bit program at 32bit and a 64bit program at 64bit. This is one of the ways that the powers to be are making the transition to true 64 bit processing. YOU CANNOT RUN 32bit SOFTWARE on a 64bit MACHINE.
it's like loading a Commodore program on a P4 .. It just won't work.
The Operon is boasting 50% faster 32bit program operation, I would assume that has to do with the massive amount of memory on the chip and the "Hyper-threading" technology, and has very little to do with 64bit processing.
The key here is to get 64bit processors out to the public. Once they hold a % of the market, The software developers will start to build 64bit software.
No different than why we need to upgrade our video cards.
