Star, I think you are misinterpreting what people have said.
The majority of people, including myself, have argued that bench placed on a lower intensity day does not provide such and extreme stimulus as to hurt training. In fact, most people have talked about incorporating it with a day off after, for example:
1-Speed / lower lifts
2- tempo / upper lifts
3- tempo or rest
4- repeat
The point being that you can spread out the stimulus and then eventually use it later, especially at higher intensities, to provide necessary stimulus near a meet.
It goes without saying that numerous elite programs alternate speed with weights anyway and still have great success. It comes down to how things are programmed either way and even in some of CF’s plans (ie GPP plan) there is some form of high intensity work DAILY (except rest on Sunday).
