I don't understand that response. Are you wondering if iCloud keychain-syncing has created the duplicate tokens? I'd say that's a reasonable idea.
 
This is the only time I've suspected it as the cause of a problem. In general I'd say it's very handy to have Wi-Fi passwords and whatnot propagated to new devices, and E-mail accounts.

iCloud has improved quite a bit since its inception.
