I guess I've misunderstood your main point .I thought the you had a problem with the position of the foot (which is at the end of the step, indeed "backward and to the side". This gives the lady the opportunity to perform a bwd walk on the next move).
Now, if I understand you correctly, the term "Normal" FWT is the issue.
Well, I've got to admit that you've got a point there, although I failed to see the definition of "normal" (in terms of "distance" and "direction").
So, I guess that what you've pointed out make sense *only* if you treat "normal" FWT as taking a "full stride" directly fwd (which I'm not sure is the correct interpretation of the term).
I'll be more than happy of any further information on the subject.
Best regards,
