Yes, this is how \txt is defined

\appendtoks \letvalue\v!txt  \itemgrouptext  \to \itemgroupcommands

\def\itemgrouptext#1%
{\def\symsymbol{\doitemattributes\currentitemlevel\c!headstyle\c!headcolor{#1}}%
    \settrue\symbollistitem
    \settrue\txtlistitem
    \itemgroupitem}

So, headstyle and headcolor are used, but not afterhead. Actually, is you 
use \head, the result is interesting :)

\setupitemize[afterhead=:]
\starttext
\startitemize
   \head This is a test

     what happens here
\stopitemize
\stoptext

Certainly not what I would have expected.
