It makes more sense to have the "ready" option take more buttons than the "not ready" option if you're forced to only give the fabled single button action to only one of the options.

If you're ready, keying in multiple actions shouldn't be an issue. If you're not ready, you may be doing something else, which would mean that keying in multiple buttons would be a much larger inconvenience to you than keying in multiple buttons when you are at the ready.
