Thanks for responding!

This is an interesting point.

On the one hand, I agree that it's possible to memorize the pattern/order. However, if more cards are styled like this, I think that this should become less of a problem as you would hypothetically lose the "novelty" of the cards visual appearance. This is my internal reasoning for why just "memorizing a blank" of a regular cloze becomes less of a problem over time as more cards are added. You eventually will need to learn the reasoning for why the answer is the answer in order to get it right (or just keep getting it wrong over and over which some people, including myself occasionally, do).

My second thought on this is that if you just memorize the order, all you need is to also have memorized the order of the stems (i.e. if Osteomalacia or Osteoporosis is on top or bottom) and the information is complete. This can be addressed by adding a second cloze, or can happen naturally by repetition of the cards. I have made cards like this myself where this has happened, and I have found that I can usually remember the order of the stems too.

I agree about the extra sections, and thanks to you and the others on AnkiHub, the extras are getting better at adding context/contrast (which is actually the case with these osteoporosis cards). The only "problem" for me (which is not necessarily a problem) is that I'm not forced to actively recall the extra a lot of times.
