The same footnote also directs students toward set theory, combinatorics, and graph theory. As I double major, I would say my study in those areas has been useful for computer science. I would guess that the recommendation to avoid "x for engineers" classes comes from the expectation that classes meant for nonmajors are likely to water down the material and reduce rigor in teaching/grading.
