That's clearly not true. He was hired as a programmer, the first in the country, by the Mathematical Center. And he wrote a number of major programs: the first implementation of the Shortest Path algorithm, the world's first ALGOL compiler, and the THE operating system -- among others. Also the BIOS for the Electrologica X1 computer, which was the topic of his Ph.D. thesis.
It's true that later on he focused on computer science theory, but to claim that he didn't know about programming shows a lack of understanding of his history.
BTW, the reason he didn't like the IBM 1620 is that you can't build a multiprogramming OS on it since it has no interrupts and uses blocking I/O.
