What does ship locking exactly mean?

Ships used in E-3 cannot be used in either E-4 medium/hard mode or E-5 medium/hard mode.

So if I use a ship in a sortie in E-3 but I did not get to the boss node I can't use that ship again in E-4 and E-5, so it is basically possible to lock all my ships from participating in the following levels? Or this only goes to the ships sunking the final Boss in the final run?
