SkeletalTrapezoidation::filterCentral never enter the if

[supermerill]

Hello
in SkeletalTrapezoidation.cpp:

void SkeletalTrapezoidation::filterCentral(coord_t max_length)
{
    for (edge_t& edge : graph_.edges)
    {
        if (isEndOfCentral(edge) && edge.to_->isLocalMaximum() && ! edge.to_->isLocalMaximum())
        {
            filterCentral(edge.twin_, 0, max_length);
        }
    }
}

the condition edge.to_->isLocalMaximum() && ! edge.to_->isLocalMaximum() is always false.
One should be with edge.from_ ?
