3.8 pf.conf question

[Rodney Hopkins <rhopkins_(_at_)_team_(_dot_)_camaroz28_(_dot_)_com>]

I was looking at the pf.conf included with 3.8, and with the 
addition of the following line:

set skip on { lo }

doesn't the lo part of the following line become redundant:

antispoof quick for { lo $int_if }

assuming both lines are uncommented?

Thanks.
