The following works for me:

    \define[2]\mycommanda{
         \startxrow
         \startxcell o#1 \stopxcell
         \startxcell \tt\WORD #2 \stopxcell
         \stopxrow
         }

    \define[2]\mycommandb{
         \startxrow
         \startxcell o#1 \stopxcell
         \startxcell \tt\WORD #2-3' \stopxcell
         \stopxrow
         }

    \define[2]\mycommandc{
         \startxrow
         \startxcell o#1 \stopxcell
         \startxcell 5'-\tt\WORD #2 \stopxcell
         \stopxrow
         }

    \definebreakpoint[mybreaks][][nright=12,nleft=12,type=1]
    \setbreakpoints[mybreaks]

    \starttext

    \setupxtable[width=5cm]
    \startxtablex
    \mycommanda{A}{lsfkgjfkgshgkhigewhgajkdkfkalhfdklahfkhaakfakfh}
    \mycommandb{B}{lsfkgjfkgshgkhigewhgajkdkfkalhfdklahfkhaakfakfh}
    \mycommandc{C}{lsfkgjfkgshgkhigewhgajkdkfkalhfdklahfkhaakfakfh}
    \stopxtable

    \stoptext

Producing:

Indeed, it produces the same when nleft and nright are both set to 1 or 
12 or 100, but not when setbreakpoints is removed.

If you are trying to do something else, please provide an MWE.
