Yeah I agree with you that they haven't really created a jellyfish. It's not much more then a muscle that contracts in the same way as a jellyfish when subjected to an electrical charge.

But if you read it all you'll notice the following paragraph, "Parker’s lab works on creating artificial models of human heart tissues for regenerating organs and testing drugs, and the team built the medusoid as a way of understanding the “fundamental laws of muscular pumps”. It is an engineer’s approach to basic science: prove that you have identified the right principles by building something with them." - This in itself is a very nice feat.
