Sorry, I think I misunderstood the problem the first time (since I didn't actually run your example until now). \setupfloats[indentnext=yes] (as I understand it) controls the behaviour after the float is actually placed in the output, rather than after the \placefigure... in the source.
I'd expect the blank line after the \placefigure to trigger indentation for the next paragraph,but this doesn't happen.
Unfortunately not, no.
I now remember seeing this problem while typesetting a thesis chapter. Going back to my source file, I see I worked around it in the most obvious way:
\setupindenting [yes, medium] \setupfloats [indentnext=yes] \starttext This line is indented as intended.
\placefigure[auto][fig:somefigure]{My graphic}{}
\indentation This is indented, but only because of the explicit command.
This line is fine. \stoptext
Maybe there is a better solution,
I hope so. Scattering the source with explicit indentation requests is not really desirable. Marco
