I think it's pretty clear that was the intent. But we don't know for a fact they would have completely wiped B4 out to bring back Data. And even if that was the intent, it doesn't mean it was right or that the books should be required to find it.
EDIT: The more that I think about it, we can't even be sure that they would have brought back Data. The only reason to really bring him back would be to keep Brent Spiner around, but with B4 they already had a character for him. I'm sure they could have found ways to work B4 into a story.
