Hi, Conni! I'm not sure which rotation you're thinking about implementing. I'll have to scan and re-post; it could be that I inadvertantly place two same-ohs together in two consecutive days that I shouldn't have.
That being said, I do think that in certain situations, depending on the exerciser's overall conditioning level AND depending on the relative intensity of each weight lifting session, it is not necessarily overly risky to work the same body parts on two consecutive days for a limited period of time. If one were to do that method over and over again, week in and week out, then yes the risk of injury would be more pronounced. However, I personally and habitually do heavy leg work on Sunday mornings (total weight load 80 lbs between barbell and weight vest, and 10.5-lb ankle weights for single-joint leg work) and do a leg-circuit cardio workout on Monday nights with a 52.5-lb barbell for the leg circuits, and that has never produced an injury. Plus, during my lunch hours 2-3 days per week I do a short upper-body set that works all of the majors (one 16-rep set per muscle group, preceded by a push-up set), simply doing different exercises each day that work the group differently.
Anyway. I'll check my rotations and see what's what. I always encourage people to do their own switcheroos with the scheduling of the rotations I post, and YOU are always the best judge of what works best for you!
