If US interest rates fall, then so will the value of the dollar. This would make the US balance of trade (and on the current account) shrink. This would broadcast recession to the rest of the world, despite its longer-term effect of stimulating US aggregate demand.
If most interest rates in the world fall in step (as with the G-7 coordination scenario that Greenspan says isn't happening), on the other hand, the dollar wouldn't change much. So there would be the effect of stimulating aggregate demand all over the world.
