No, it is not like SIMD. It's more like an ALU, in that there needs to be gates present for each possible operation (and then muxers/demuxers route through the correct one).
Something that is like SIMD in quantum computing is that if a block code supports a transversal operation then it is far cheaper to apply that operation to every qubit in the block than to selectively target one of them with the operation.
