It's a side-effect of 'smartindent' ('si').

From :help 'smartindent':

"""
An indent is automatically inserted:
[...]
- After a line starting with a keyword from 'cinwords'.
"""

Default value of 'cinwords': "if,else,while,do,for,switch"

So, it's because the second line starts with 'for'.

In my experience, 'smartindent' is rarely smart. Most languages to
which it might apply already have smarter indent functions. And outside
of programming, you definitely don't want it turned on.
