In Javascript, what does "if (x) x  =" mean?

I'm writing an auto-complete script little by little (html/ plain javascript/ php/ ajax).

I've come across the following code:

var x = document.getElementById( + "autocomplete-list");
if (x) x = x.getElementsByTagName("div");

... and would like to understand this particular bit of the above code

What does the following bit mean? I've never seen logic like this before.

if (x) x  =  

Is this a comparison / some kind of logical operator? I'm wondering if it's a way to detect whether x is NULL and so get information from the immediate parent element. Nevertheless, I'd like to understand what it means.

If so, in 'long English', what does it mean?

Thank you
