I just connected two scrolls.
The "flow" is maintained - the second scroll optically departs from the inner part of the first one following the red line. So you see that I could also have done this and use a normal inner leaf instead of the connection.
The blue line tells you that the connection could be seen as a "starter" for the inner part of the frist scroll. An element that is not needed here, but the connection is in correct in CW - CCW sense.
