Spanish follows the English order, unless given its own

Lucía has written Spanish versions of every row in the Writing curriculum. Then Ben reorganizes the English outline and moves Lessons 2 and 3 into Topic B. Does the Spanish outline change too?

That depends on each Spanish row. A Spanish version starts out following the English order: it has no place of its own, so it sits wherever its English row sits, and moves when that row moves. Once someone places it in the Spanish outline on purpose, it has a place of its own, and English moves leave it where it is. Lucía did that for Lección 3.

Try it: select Lesson 2, then Lesson 3, and compare where each one is in English and in Spanish.

Lección 2 had no place of its own, so Ben's move took it along: it's in Tema B, as Lesson 2 is in Topic B. Lección 3 has a place of its own, marked “Own place in Spanish”, so it stayed in Tema A. In your work, the Spanish outline keeps up with the English one until someone places a Spanish row on purpose. From then on, English moves leave that row alone, and if it should move too, someone moves it in Spanish.
