Doing a forward assist could potentially jam a malformed round into a chamber, or a normal round if the chamber was really dirty. However, the force of the gas system on the bolt is stronger than that of the bolt spring (otherwise the gun would never cycle) meaning that if there is too much friction in the chamber to prevent the spring from locking the bolt hence requiring a forwards assist, the gas pressure would normally be more than enough to overcome this friction to extract the round. Also, I think that there would probably still be a slightly higher pressure in the chamber giving the case a slight blowback effect.
