How do the Family "Warp to" and "Warp them here" skills work?

For a while now, I've put all of my lower leveled characters all the way down to a level 1 in maple island into a single family and I've planned on linking it up with my main whenever I got the chance (primarily since I don't want to be an untraining burden on anyone). The main reason I'm doing this is so that I can become entirely inactive and at the same time, be able to go anywhere instantly should I come back for a moment to meet up with people again.

A while back I tried to use this skill between two of my alts and it kept saying that the character was not logged in. They were on the same channel. What I want to know, yet will really be disappointed in if true, is do those warps act as a VIP tele stone, or only a regular tele stone. More simply put, can the family skill teleport you across continents.


EDIT: Yes, I'm aware that as things stand now, there is no way back to maple island.
