You can add a check for odd/even chapter numbers and use only a single 
command.

\startsetups[chapter:after]
   \ifodd\namedheadnumber{chapter}
     \blank[4cm]
   \else
     \blank[1cm]
   \fi
\stopsetups

\setuphead
   [chapter]
   [after=\directsetup{chapter:after}]

% \setuphead
%   [title]
%   [after={\blank[...]}]

\starttext

\dorecurse{10}
   {\chapter{Chapter #1}
    \input knuth}

  <p>Thanks Wolfgang. Clearly that fixes the problem. I also came up
      with another solution which avoids the need to define a
      MyChapterCommand, by first setting up the normal chapter as:</p>

    
  <p>\setuphead<br>
        [chapter]<br>
       
[header=empty,alternative=middle,style=bold,numbercommand=\groupedcommand{}{\blank[2cm]},after={<font
 color="#f8070d">\blank[3cm</font>]}]</p>

    
  <p>and then setting up a mychapter as:</p>

    
  <p>\definehead[mychapter][chapter]</p>

    
  <p>\setuphead[mychapter][header=empty,alternative=middle,style=bold,numbercommand=\groupedcommand{}{\blank[2cm]},after={<font
 color="#f8070d">\blank[.5cm]</font>}]</p>

    
  <p>That gives me the result I am after as well as maintaining the
      style of the standard chapter head.<br>
