Is this some form of foreshadowing?

I have a gut feeling that this is a soft form for foreshadowing to the end of season three, whereby the previous frontman (Oh Ii Nam) tells In-Ho that sentence of “I’m your father” to kickstart season 4 - The backstory of In-Ho and how he rise to become the current frontman and how this might convince GiHun to be the next frontman.
