Firstly, he built the Apple 1 with a 6502 before the Apple ][, which was a major improvement on the Apple 1.
He had designed the Apple 1 on paper before the 6502 was available. He had preferred the Motorola 6800 processor but couldn't afford it at $170 ($925 in 2022 dollars). Then when the 6502 came out priced at $20 ($103 in 2022 dollars), he used it instead.
So the KIM-1 had no bearing on the Apple 1 or Apple ][.
