The manual says you're in charge of ensuring that in

is, H doesn't seem to matter at all, unless it's nil:
Actually H is also useful if N is nil (that is a tail-append the list
that starts at H), but it is true that H is generally unused.
Good to learn that "node.insert_after(H, nil, x)" is equivalent to
"node.insert_after(H, node.tail(H), x)". I'd always wondered why there
was no shorthand to append a node at the end of a list.
Best,
