do you mean that after someone depart from the true faith, after they discard their believed on Jesus as their one and only salvation, they are still saved and sealed?
bible is very clear on this!
2John 1:9 Whosoever transgresseth, and abideth not in the doctrine of Christ, HATH NOT God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
Hebrew 6:6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
you CANT crucified the Son afresh and put Him to an open shame!
dont even try crucified the Son afresh!
truely fanatic of The Truth 
A believer can depart from their faith, but they cannot depart from their salvation.
We are sealed!
