possible issue w/ ddt make-it-so

When doing:
drush @thing1 ddt @thing2 --make-it-so --y --components=modules

I was able to get it to supply uri of @thing2 instead of @thing1 when it did the options cascade. Need to dig deeper. In this instance make-it-so just won't apply it, it doesn't hurt anything as it's just supply the settings back against itself but it won't make the two targets equal. Previous testing showed this wasn't the case but this occurred in the wild.
