So, "penetrate" means to cross, not to fly through or teleport? :)

The concept of "penetrate" includes the concept of flying through/teleporting.
But with Wings (Flight, Jump), it's not necessary to break through the guard of the respawn point (applicable to many map designs, in particular 2sm4d(3)).
