I like that orthagonal suggests that they definitely intersect, but go in two different directions. Unrelated is too harsh in most of the situations you'd use orthagonal.

Well, orthogonal lines don't have to intersect in in geometry (you just need more than 2 dimensions), and "intersect" is meaningless in algebra. So, I don't think that's really implied.

Criticizing jargon in the field of programming because it's not used in exactly the same sense as when it's jargon in mathematics is.. weird.

Ah, yeah, that's true. Though some developers use it without that context to really just mean "unrelated".
