Without trying to understand the code flow in init.c, is there a
deeper reason why this happens twice?

... and here again, but only sometimes?
server code path. The client has no tuntap object when passing here
(it's done quite early, so we need the previous snippet).
The server executes this code for each new client.
I hope this clarifies.
