[web-animations] no 'add' in iteration composite operations

Hello, everyone.

It looks strange, that iteration composite operation
( https://w3c.github.io/web-animations/#iteration-composite-operation )
defines only two operations: replace and accumulate.
While there are three operations for animation composition:
replace, add and accumulate. (  
https://w3c.github.io/web-animations/#animation-composition )
Could you explain why 'add' is excluded?
Is it typo or there is some reason?

Thanks,
Aleksei.
