Just to add more,he partially uses F1 too, I've observed it by myself, this is a function of VCMPHACK.asi, which instantly quits your game with a timeout message, also, it's not possible to quit with a timeout message if you're using windows 10,I've did quit several times via task managing ending process thing, I got to see quit message on IRC channel.
To add more, common timeouts take time, for example, ripping your net cable or matter of power cuts (he's not living in Pakistan or India to have it) it takes more time, probably 10 seconds, but this escalated quickly,just what F1 mod do..
