I’ve modified the MWE to avoid the \\ and it shows same problem. I’ve used the \\ to make a par with 2 lines (lazy typing more words :-). In any case \\ or not, the \hang* directives do not seem taken in consideration in this particular case for last par. Other cases seem to work fine.

%\setuplayout[grid=both]
%\enabletrackers[vspacing.synchronizepage]

\starttext

\dorecurse{39}{
A.

}

Chapitre.
\blank[0pt, samepage]
\hangindent=30pt\hangafter=-2Third par with some lengthy sentence. Second sentence. Third sentence. Fourth sentence. Fifth sentence.
\blank[0pt, samepage]
\hangindent=30pt\hangafter=-2 Fourth par not indented. Lengthy sentence. Second sentence. Third sentence. Fourth sentence. Fifth sentence.

\stoptext

it's probably more related to the wrong usage of \\ which you normally 
should not use at the end of aparagraoh (i'll make the remover for that 
a bit more clever)
