Ladon vs. Python

Was wondering if both powers trigger in this situation: if Ladon enters Pyrhon's area he triggers Python's Strike (auto 5 dice attack), would this auto attack trigger Ladon's Many Bites (4 dice attack before being attacked)? All this before Ladon actually does his activation

I think it should go in this way:

1. Ladon enters in Python's area and he triggers Python's Strike.
2. Python's Strike activates Ladon's Many Bites.
3. Resolve Ladon's Many Bites.
4. Resolve Python's Strike.
5. Ladon resolve his normal attack (if he didn't make a complex action before)
