It can happen that custom resamplings have exactly the same instance but are instantiated on different tasks.
I would still expect these resamplings to have a different hash.
This case actually happened to me (OpenML task splits seem to be deterministic, i.e. when tasks with the same number of observations are uploaded, the same task split is generated).
