Yes that's the case. I thought it would count these, but looking deeper into the code I can see it wouldn't count them even though it maybe should. See https://matomo.org/faq/how-to/faq_21824/ it is only their to correct the visit duration, but not to keep the session active. It was initially implemented like this, but then changed due to couple of problems. For example you would see visits with several hours etc.

Are you familiar with PHP ? You could create a plugin and put this file into a Columns directory to change this behaviour:

./console generate:plugin --name="YourPlugin"

namespace Piwik\Plugins\YourPlugin\Columns;
use Piwik\Tracker\Request;
use Piwik\Tracker\Visitor;
class VisitLastActionTime extends \Piwik\Plugins\CoreHome\Columns\VisitLastActionTime
{
    public function onExistingVisit(Request $request, Visitor $visitor, $action)
    {
        return $this->onNewVisit($request, $visitor, $action);
    }
}
