But to emphasize one quote from the blog: "the new experiment doesn’t add anything new to this old debate" about multiverse interpretations vs. something else. An equally viable and perhaps conceptually simpler interpretation of the experiment is that the qubits are temporarily put in a 'superposition' of many different bitstrings, some operations are performed, and then measurement collapses this superposition back into a single definite bitstring. No multiverse required.
