if you say \showstruts you will notice why you need to skip back; your 
4pt is a gamble, best do something:

\defineenumeration
 [example]
 [way=bychapter,
  separator=\compoundhyphen,
  chapternumber=yes,
  color=white,
  command=\exampleframed,
  inbetween=\setups{example:inbetween}]

\startsetups example:inbetween
    \removedepth     % nils strut depth
    \nointerlineskip
    \blackrule[height=1.5pt,width=\hsize,depth=0pt]
    \blank
    \nobreak
\stopsetups

btw, this makes a nice example for a regression test
