To my taste, this would read better as 

If (vp == boundaryInDirection(vp)) {
    boundary = vp;
    break;
}

auto position = useDownstream ? previousSentencePosition(vp) : nextSentencePosition(vp);
boundary = boundaryInDirection(position);
break;

More granular to step in a debugger and diff in a source control tool this way too.
