Probably not relevant anymore, but I'm pretty sure some people have doubts around the 9:00 mark about why (1,9) and (3,11) aren't paired together - after all this would technically form -0-1, which would make sense right? However, this isn't a possible pairing because the second pairing you are trying to merge has a value lower than the last value in the first pairing So, if you notice throughout all of the pairings, the right hand value is consistently at least larger than the left hand value for example, (1,3), 3 is greater than 1, (3,7), 7 is greater than 3, (9,13), 13 is greater than 9 This same concept is carried over to pairs with two dashes or differing bits: (1,3,9,11): 1 < 3 < 9 < 11 (2,3,10,11): 2 < 3 < 10 < 11 (3,7,11,15): 3 < 7 < 11 < 15 A pairing of (1,9,3,11) would break this rule: 1 < 9 !< 3 < 11

@@berserk8914 stop the video at 9:30 and you can see he just finished writing two of those sets of numbers in a different order. As for the (9, 11, 7, 15), that isn't a possible combination since 3 symbols change.
