Can you please clarify this for me.

It is always the case. The ground is a continous path to earth to protect users. The neutral is a continuous path to earth to carry load. Without a ground wire the hot can touch metal making it live and when you touch it you get a surprise. If it is grounded, it arks sparks and pops a breaker long before. If the metal of the case is touching neutral, you would know nothing of it until your neutral path to ground is broken for some reason at which time it will become live, if not grounded properly.
