Not in that particular reddit discussion, but that topic is partially covered in the Ledger Recover FAQs. I say partially because they don't go into details how the recovery is supposed to work if the original device is lost. Check the answer to the question "What if I lose my Ledger device that is associated with my Ledger Recover subscription?" o_e_l_e_o is surely on the right track here.
Considering the documents on the FAQ page of Ledger Recovery and how Ledger is replying on Twitter, I would say that o_e_l_e_o is exactly right regarding how the process will be deployed. What amazes me is the fact that Ledger is totally silent when faced with the fact[1][2][3] - or flaw - that is being able to restore your encrypted shards on any device. Do they consider their clients that ignorant regarding how seed phrases work? I should also note that Ledger Nano S will eventually[4] receive this "awesome" feature, per reply on their Reddit page.
