the Traffic (2) and Traffic (3) are same at Listed Pages, as you can see each of the 8 listed items.
The difference is on the "Total".
It seems to me:
In Traffic (2), it is the total Accumulated visits, 48K visits is a sum-up counts, if a visit come to Page 1 then Page 2, then there will be 1 visit to page 1, 1 visit to page 2, so on the top of the table, it is 2 in total.
In Traffic (3), because of the "OR" criteria is applied in the HIT level segment, if a visit come to Page 1 then Page 2, because of the segment is applied in the table, so the count of visit for the segment item is displayed as 1 besides the segment.
Which means, there are about 17K visits visited more than 1 page in the "visiting journey".
