Right. Trivia: When you "start using" a stack, its script is inserted 
ahead of the Home stack (for HC compatibility.) When you insert a 
backscript, the script is inserted behind the Home stack, closer to the 
engine.

In the MC IDE (and also the Rev IDE I think, but I'm not positive) it 
doesn't matter since Home doesn't insert its own script in either way. 
But in a standalone, the main stack acts like the Home stack and it may 
make a difference which syntax you use.
