Because it's not a push_back.

push_back(c, v) is a mutating operation on c. After it c has one additional
element pushed to its back, v.

append(a, b) is a pure function that returns the concatenation of a and b.

I might be wrong, though; it's been a while since I looked at anything
Lisp-related.
