Inconsistent Redirect method

I think there might be an issue within the Laravel code, but may be I see it wrong, but the redirect response methods seems not consistent to me. I used the following example

    $router->put('check', function (\Illuminate\Http\Request $request) {
        return redirect('/');
    });
    
    $router->put('/', function (\Illuminate\Http\Request $request) {
        echo 'PUT';
    });
    
    $router->get('/', function (\Illuminate\Http\Request $request) {
        echo 'GET';
    });

If I'm using a "native" HTTP PUT request (via HTTP client or curl) I will be redirected to "PUT /" , but if I'm using a HTTP POST request with a "_method=put" parameter I'm redirected to "GET /" . Do I expect a wrong behavior or is this an issue within Laravel? I'm using the Laravel Framework Version 5.2.35.
