That happened to me last weekend. I was riding on a street I have never been on before. There was a huge steep climb and directly at the end is the end of the street and heads into a busy street. So basically I had to stop on the hill, pulled my left foot out and lost my balance and fell right. Actually fell into a pile of snow so wasn't too bad.

Only 2nd time I have fallen with straps. 1st time was a few days after getting my toshi singles and thought I had them loose enough to get my foot out, but couldn't. Possibly got stuck, I don't know. But just fell over.

These falls are so weird since you just see the ground getting closer and closer. Then you feel the ground.
