I’m using decks of the Basic (and reversed card) type, and I am presented with one version immediately before the other quite often. Sometimes it is normal immediately followed by reversed, and sometimes the other way around. This doesn’t always happen, but it seems like more often than chance. This doesn’t test me on the second version, because I just saw the front and back. I would like to see the normal and reversed types always separated in the review sequence.
There are plenty of ways to avoid that already –
