Bash manual says that Expansion  is  performed  on  the command line after it has been split into words.. However, in the next sentence it states that there are seven kinds of expansion performed and word splitting is the sixth one. As I understand, those two are different word splittings. What is a difference between those two word splittings?
Difference between word-splitting before expansions and word-splitting during expansions in bash?
bash;bash expansion
