With a typical OoO CPU you have reorder buffers in the hundreds of instructions, so you are not speculating two or three branches but potentially dozens ahead of non-speculative execution (and that's why prediction accuracy is so important). So the question remain, what's the innovation here? I'm sure there is something, but it is not simply speculating two ahead. I need tor was further, bit this might be an optimization in the fetched tage to avoid a bubble when fetching consecutive taken branches.
