If a person has an opponent in reverse mount on them...will the person always be able to get to their feet...?

[Heart of the Matter]

...if the person knows proper techniques to do that?

I am thinking that perhaps in a real life encounter (with hard cement and sharp things around)...it would be better to give up the back, rather than be mounted....
to protect ones own neck, then turn over...BUT...ONLY if the person can always stand up...to be able to do slams and stuff...
