Why? "imperatively executing statements one after the other" does not imply that they have to be on different lines.

They don't have to, but they are, most of the time. Knowing that, "newline as delimiter" yields the lightest syntax.
Actually that would be an argument for making newlines delimit statements, like in, say, Python. Instead of requiring extra work by the programmer.
