That works for me, and is what I do 90% of the time . . . with the only exception being WODs that I just can't do (e.g., 30 minutes of muscle-ups).
Again, just for the record, I guess I should note that I'm a 48 year old deskbound guy with a family and no real athletic aspirations beyond being fit, not getting fat, and being able to ski in the winters. For these goals, it really doesn't matter whether my training is perfectly optimized . . . CrossFit is so much better than any alternative that I can easily reach those objectives.
If I was trying to compete at something (judo again? (I used to do that . . .)), or if I had a job where my physical condition mattered (LEO), then I'd be taking the nuances of workout sequence more seriously.
