Working with nextSibling as a solution for inserting after the element

I've used 

ul.insertBefore(li, nextLi.nextSibling);

not 

ul.insertBefore(nextLi, li);

and the code is working fine. Is it ok to solve it this way?

Technically, it's equally effective as a solution, but it's a bit more complicated. Plus it relies on the new item being inserted at the end when "nextSibling" doesn't exist (and returns null). That could potentially confuse readers who are not intimately familiar with the operation of "insertBefore".
