If I change the line containing that in my MWE to
\setupheadertexts[top: {\getmarking[TestMark][column:top]}][bottom: {\getmarking[TestMark][column:bottom]}][top: {\getmarking[TestMark][column:top]}][bottom: {\getmarking[TestMark][column:bottom]}]
or
\setupheadertexts[top: {\fetchmark[TestMark][column:top]}][bottom: {\fetchmark[TestMark][column:bottom]}][top: {\fetchmark[TestMark][column:top]}][bottom: {\fetchmark[TestMark][column:bottom]}]
then the problem is not fixed. Is this what you had in mind, or were you suggesting to use it in conjunction with the column number as a second argument? In that case, the line would look like
\setupheadertexts[top: {\getmarking[TestMark][1][column:top]}][bottom: {\getmarking[TestMark][2][column:bottom]}][top: {\getmarking[TestMark][1][column:top]}][bottom: {\getmarking[TestMark][2][column:bottom]}]
If I use that line, then I do get markings from the first column (i.e., the right column in this case), but they don't seem to be correct; marking 1 isn't referenced in the header of the first page, and the first new mark on the second page is treated as the top mark for that page, rather than the current mark at the time the second page begins (which may be correct, but still does not seem consistent with the behavior on the first page). If this is the correct behavior, then is there something I should change in my syntax to make marking "1" appear as the top mark for that page?

what if you prefix with column:, like column:top and so
