First of all, the Anki 2.0 is better compatible with MN than 2.1 about Video cards.
The emphasized words could be cloze (or not ) in Anki just as one except to one card correspondence at present. This means Anki not support it.
According to my test, although I edit export from MN as what you said. It also dosen’t work for anki.
It is said multi-cloze works well when Anki still in 1.x. If you found the way make Anki support this. Please notify this thread and I will do further test.
