In GHCi we can redefine a data declaration; last definition counts. But loading a module has a side effect of bringing the first declaration to front:

λ> data A = X
λ> data A = Y
λ> :i A
data A = Y 	-- Defined at <interactive>:3:6
λ> :m Data.List
λ> :i A
data A = X 	-- Defined at <interactive>:2:6
