difference in minimmum velocity for vertical circular in rod and string

The particle will complete the circle when at the highest point if the string doesn't slack at the highest point when θ=π." - Is it because if the rope slacks, then the mg component will pull it inwards and so the particle will not move as a circle?
When we talk about conditions for the bob to oscillate (u <= sqrt(2gR)), why do we say that velocity must be equal to zero before tension is equal to zero? And likewise for conditions for leaving the circle, why should tension be zero and velocity not 0? What really is meant by leaving the circle? Is it like following a different parabolic path for some time? Please illustrate.
