What exactly is the difference with \placefigure[left,none]{}{\externalfigure[cow]} and \starthangaround{\externalfigure[cow]} ... \stophangaround

\starttext
\subject{Flowing text}

Now text with a few figures.  The first figure goes on the right, with
the paragraph flowing around it.

\placefigure[left,none]{}{\externalfigure[cow]}
\input tufte

\starthangaround{\externalfigure[cow]}
\input tufte
\stophangaround

\stoptext

The output of the above shows that both are similar with placefigure having extra White space, but is it semantically different?
