No, isa() returns true if whatever method isa() is for the invocant it returns true. If I wrote an object and overrode isa() to return true based on a the phase of the moon, that's what it would do.

That's probably unwise code to write, but the purpose of having isa() be a method is so that classes can override it when it makes sense to do so.
