When a rule says 'insert 2.a', does that mean the rule is inserted before or after the main rule 2 in the normal cleanup sequence?

Ruling: When a rule says "insert 2.a", it means the rule is inserted after the main rule 2.

Nuances:

• This ordering matters for effects like Kog'maw's, where inserting after rule 2 allows combat damage to sum with deathknell damage, while inserting before would not.
