I have never seen that happen, thats too much heat too fast in one area, thats why i said go slow, i have seen this done several times and it worked great. On the same side cutting coil springs is not recommended as springs In most cases are progressive, which means they have a different spring rate top to bottom, replacing the spring is the best thing to do in all cases.
