I reported the similar issue before.
ast.Merge doesn't update ValueHeadComments.

go-yaml/ast/ast.go

Lines 1473 to 1478 in 5d22eed

	// Merge merge sequence value.
	func (n *SequenceNode) Merge(target *SequenceNode) {
	column := n.Start.Position.Column - target.Start.Position.Column
	target.AddColumn(column)
	n.Values = append(n.Values, target.Values...)
	}

✅ I'll create a pull request to resolve this issue. #570
