How is transient response affected by moving the pole in presence of a zero?

[iVenky]

I was reading about LDO. In there as the load current increases the non-dominant pole and RHP pole move to high frequency while the LHP zero doesn't change. I have no doubt in this. But what it says is that the transient response slows down as the load current increases because of the above statement. Could you please explain me this?

I have attached the response for both conditions.
