They go into a bit more detail about possible explanations here (this is cited in the paper that the article talks about). https://arxiv.org/abs/2006.14805 They talk about your option in 5.11, "Einstein rings." For reasons that I don't understand (but I don't understand anything about optics) they come to the conclusion that the gravitational lens would have to be really large, and it is unlikely that such a large, well-structured lens would exist.

paper: https://arxiv.org/pdf/2006.14805.pdf > Frequency range: 800 – 1088 MHz > Total integration time: 100 hours but then > We observed ORC 1 and ORCs 2–3 (Project code C3350)with the Australia Telescope Compact Array (ATCA)on 9–10 April 2020, at 1.1–3.1 GHz (weighted centralfrequency after the removal of radio frequency inter-ference = 2121 MHz), over a period of 2×12 hours and > ORC-4 was found in archival 325 MHz GMRT data

Maybe better to just read the arxiv article, linked in OP. It's quite readable for a lay-person such as myself, and the meat is quite short. There are pictures starting page 23. https://arxiv.org/abs/2006.14805
