The added latency can't even be measured in milliseconds, it's basically non-existent.
Imagine chaining an analog mixer into itself. Plug a mic into input one, turn it up on the main mix, and then send the main mix back into the mixer on input 2. If you were to monitor that with headphones, the added delay would be imperceivable.
Also take into consideration what an ADAT expansion does, like the RME OctoMic XTC. You send a mic over ADAT from the OctoMic into your interface with no perceivable delay. Though in the case of looping an ADAT connection into itself there's even less delay, as the signal doesn't need to be converted from analog to digital or vice versa like it does on the OctoMic.
