you are confused about "selling 2 puts"

Still lack fundamental undertsanding of "spread".

There is only "1" put being sold in the ratio spread, not 2. The first spread (buy 1 480 and sell 1 465 is neutral and will net in "0" put position.  Only the 2nd sell 465 results in 1 put position). Therefore, you can not compare this with a stratgey to sell 2 465 put.

Really suggest you read up books and study more. You concept is all wrong, and it  could hurt you in the hedge. This just can't be explained on a forum like this
