An assumption that nobody else has stated, hinted at, or “argued” in this thread.
I’d expect that requiring a larger number of upper level CS courses typically corresponds to learning more CS specific material. This might correlate with better chance of acing the tech questions during first CS job interview and being hired, or slightly better average earlier career performance in a CS-specific job. It probably also has some influence what the school is known for among both students and employers, which has some degree of influence on which students choose to attend and which employers choose to recruit. However, this is speculation. There is no way to test whether true or not.
Looking at a single extreme outlier is not particularly meaningful for drawing conclusions, even more so for fields where graduate degrees with additional courses in major beyond the bachelor’s course hours are often expected.
