The blades do not ever cross paths, at least I've never seen it, normally nor with Serial Torture so the first telegraph is already telegraphing the second. "^_^_" means the other set will be "_v_v", "^^__" means the other is __vv", and so on.
So there's really only three telegraphs to worry about, even if the attack is 4 steps. Cutting redundant actions, in this case checking position for the second blade set, helps with reaction time.
