Jan van den Velde's backslanted letters

I came accross backslanted text in a few plates from Jan van den Velde's Spieghel der Schrijfkonste and came to wonder what it stood for.
In the examples I found the text seems to be introducing something else but I can be wrong.

Any help, references or other examples would be much appreciated!
