You must not reuse IV between different blocks, but that does not stop you from using the same IV for the same block. Yes, you leak information about matching blocks - it's up to your use case whether you care about it.

Yes, sorry I was imprecise. I meant reusing IVs for equal blocks only, to be able to see duplicate data.
