No Edo Tensei Mangekyou Sharingan is not an Eternal Mangekyou Sharingan. the Mangekyou and Eternal Mangekyou are not the same eye, when two uchiha closely related(closer than regular uchiha) such as brothers or parent and sibling transplant there eyes in rare cases the person who transplants the eyes gets a brand new Eternal Light for the eyes. its not just an eye that doesn't go blind from excessive use though, its a completely different eye. Madara stated that his Visual prowess was the combined prowess of him and his brother. you see when sasuke transplanted itachi's eyes and the eyes evolved into the Eternal Mangekyou, his clarity of vision increased exponentially. lets put it another way. lets say the byakugan has a similar type eye in which two hyuga of close relations transplant there eyes into each other. lets say this new eye is so efficient the person doesn't have any of the drawbacks of overuse such as severe but temporary eye-strain. and then combines the two visual prowess of both byakugan. so lets say Neji's curse mark was removed before he died and when he died he told hinata to take his byakugan and transplant them. now early on neji could see a distance of at most 50 meters away and by part 2 he could see 800 meters. Hinata on the other hand was able to see around 10 kilometers so combining her byakugan with neji's would have allowed her to see around 10.8 kilometers. by the time of naruto the last movie its stated she can see 20 kilometers so if neji was still alive in the last it can be assumed he could do a similar feat so combining there visual prowess together would mean the new eye could see 40 kilometers. now do you see it. merging two dojutsu creates an eye that is supremely more powerful than the eyes before hand
