Randy didn't know what could allow his incarnation to accomplish such a feat since he was originally a defective creation. Furthermore, he did not recall having any precognitive ability, so he didn't know how his incarnation could have such an ability to plan instinctively.
Another thing he noticed was his fearless behavior when confronting others and his mysterious aura that was unlike the boundless murderous aura he exuded. That aura his incarnation exuded was more fierce, imposing, and commanding. On the other hand, the murderous aura he possessed seemed to contain an aura of death, capable of inducing apprehension, hallucination, and terror into any living being.
Randy decided to dismiss the actions of his Incarnation after realizing that it was actually helping him knowingly or unknowingly by planning ahead. Although he didn't understand the mechanism behind it, he acknowledged the potential of such an ability.
