Did anyone see the seek invite function from patch note?

"[dev1079] Two new options have been added to the party search and recruit features.
Instanced Raid
Seek Invite
* Players using "Seek Invite" as their purpose when searching for a party will appear in recruit searches only when the recruit purpose is also set to "Seek Invite." "Purpose: none" recruit searches will not turn up players who have set their searching for party purpose as "Seek Invite."
"

I don't get the system and don't see anyone using it. This could me just me.

What do you guys think?
