Im guessing the reason the two links are worded the same is because there are two ways you can "hug" the same post...you can click the word "hug" and your hug will appear ****underneath**** the post the post/poster you are "hugging" and the send way to "hug" a person is to make a reply post and actually write the wird "hug" or place the persons name in a set of brackets like so (((((name of person being hugged))))) which is internet version of giving a hug.

one link designates the hug ****underneath**** the post
one link designated the hug in a written post..

they are both the same post being hugged.

thats my guess anyway.
