I love this style of code reviews and it's the one I've experienced best discussions with. It goes in line with assuming that you, as a reviewer, don't know what the intentions/rationale are rather than blindly dictating your solution. A lot of times the reviewer that says "this is wrong" is then explained to why it was done a certain way and is the one proven wrong. Questioning yourself as a reviewer is always a good idea. Asking questions gives feedback without coming off aggressive/judgemental/patronizing.
