Is filter is in with a string the same as filter OR =

AIP Generate made the following expression and I want to make sure the two are equivalent and that my pipeline isn’t doing a string contains characters on the string rather than string equality, as the docs for the Is in board suggest it only accepts arrays not single strings (and in python for example is in on an array would do string equality, but is in on a string would check if it was contained).

Simple question is if the two of these are equivalent or not?

IsIn will return true if at least one element of the array equals the value.
