It's not a circular reference, you just didn't know the original work and started accusing Apple's design of being a rip-off. That's simply 'getting it wrong' not 'circular reference'.
Apologies for that. I knew the 2010 piece was done by a Spanish designer and they looked extremely similar. What I did not know was that the 2010 designer was inspired in previous Geoff's work.
The circular reference I was pointing out:
Geoff's Work ->(inspired) Rocio's work -> (looks extremely similar to)-> Geoff's work
UPDATE: Apparently she did it inspired by Geoff Mcfetridge's work, SO we have a circular reference lol
