Use of "ee" in Q2-3 is weird(?)

[Bluetoes101]

There are others without ee but not too many, in different distribution than the initial one shown. Makes me wonder if maybe some pages are flipped or out of sequence and that maybe a better order can be found if this is indeed a thing. In the second half of the manuscript, ee appears to occur on every page.

I think "ee" is more a "b thing" than "a thing" in general, but the way "a" goes about it is a bit odd.
I have no clue why this would happen but sort of interesting that it does
