Going along with your reasoning I will conclude this, time has alredy been altered by Impulse but he is still in the past (As Peter David said when time is changed it accommodates the revision made from that point on) meaning he has a whole new plan on how to change the future (according to time now Flash was not killed by Neutron) ergo any time he changes the past and is still in that time line (because the past was changed and the future is better he would have no reason to go back in time) he will be prepared to deal with the new altered present and future.
