All are true about functional divisions of liver EXCEPT:

Gray's Anatomy mentions three major fissures (not minor) in the functional division of liver. Functional anatomy of the liver is based on Couinaud's division of the liver into eight functional segments based on the distribution of poal venous branches in the parenchyma. The liver is divided into four poal sectors by the four main branches of the poal vein. These are right lateral, right medial, left medial and left lateral. The three main hepatic veins lie between these sectors as intersectoral veins. These intersectoral planes are also called poal fissures namely: Main, left and right poal fissures. Each functional segment receives its own primary branch of the hepatic aery and hepatic poal vein and is drained by its own hepatic duct.
