I don't think the changing partners is relevant because 60r is all by itself, even though 60v is clearly, by the text, the next move after 60r, but it has a different partner. The wind he is doing is also a natural follow up from the position he is in on 59v. Instead of showing the wind on the left side of the blade, as is more typical, his is on the right. Also, if we assume that the opponent is successfully defending himself, and thus the continuation of a series of winding actions is necessary and shown in this series, then it would seem that his opponent would have been backing up. So, only be one step, not two, is necessary.
As to him being portrayed left handed. He is, in the longsword section, only left handed in presenting the Alber ward. And both he and the other presenter showing vom Tag are left handed on that frame. Here is another version showing the same left hand Alber:http://wiktenauer.com/wiki/File:MS_1825_18v.jpg
I don't think that is an error. Though I do see a possible disconnect between his position on 61r to 61v. His mutir doesn't seem to follow from his duplir. Except that the duplieren shows a clear line of attack, almost hitting his opponent, so this could also be looked at as a place where the opponent has to back up.
In the expanded version, two more versions of this series are shown. The first version, the Munich is what I started with. The expanded includes the images from the Bologna and the Vienna editions. The Bologna shows the more standard step out in the wind. The Vienna is almost identical to the first, but doesn't show facial features and other details. A fourth version, the Solothurn is there too, but it lacks the full set if plates:http://wiktenauer.com/wiki/Paulus_Kal/E ... .9Ffechten
The idea that these are a series of continuous actions is most evident in the Bologna edition. Which supports my claim that the Munich series is a continuous set, though not for my alternate interpretation of the wind. The Bologna version of plate 59v clearly shows the opponent moving just look at his feet. It looks like he is stepping forward and the attacker has to step out and to his left for the wind in 60r. This is consistent with my idea that against a hard bind in the center with forward momentum, it is better to step away from the direction of the wind thus allowing my opponent to carry forward and using his momentum to make the stab to his face more effective. But to get more evidence for the step into the direction of the bind I'll have to look at later manuals. I'll have to get back to you later for that...
