Actually the authors dutifully note this case, explaining that "we show that cold boot attacks are more generic and allow to retrieve sensitive information, such as contact lists, visited web sites, and photos, directly from RAM, even though the bootloader is locked."

But this isn't nearly the end of the world scenario the article seems to paint. And also on more recent Android devices you cannot even perform an unlock of the bootoader without knowing the device PIN. Try it on a nexus 5x/6p/9.
