Need Help > Parasoul Combo

[cocasem]

First, I would like to say that I have a bad English skill.
If I use wrong grammar, I'm sorry for that. Please forgive me. :(

I practice Parasoul's combo just like in this VDO(at 01:34 to 01:46)

So it's look something like this

→ LP > c.MK > c.HP > super jump > j.MP > j.HP > j.HK > land > s.MK > s.MK > s.HP > s.HP > ← → LP > s.LP > s.MK > s.MK > s.HK > ↓↙← + MK > jump > j.LK > j.HP > ↓↙← + LK > land > j.LP > j.LK > j.MP > land > j.MK > j.HK > ↓↙← + LK > land > c.MP > s.HP > s.HP > ← → LP > s.LK > s.HK > MP+MK(change character to Filia) > dash > s.HP

I have some problems.

1. After I shoot the last ← → LP[napalm shot] >s.LK, I trigger IPS(or Infinity Breaker). I don't know why. o_O
2. If I start practice shoot s.LP[napalm shot] > s.LK > s.HK > MP+MK(change character to Filia), I can't dash + s.HP to link the combo. Why? (VDO at 01:47 to 01:48)

Could someone explain this to me, please?
