No. The rule is saying: Do not add instance index properties OR custom
OF aliases.

Logical "OR" means here that for you this sentence is equal to:
"Do not add custom OF aliases."

It's true though that you did not add custom OF alias, but a generic
alias, yet you did not explain anywhere what this generic alias means as
an ABI.
