No, it's the same door you know about however I think a lot of players did not realize you could use this to get to Mantis Den/Smugglers (myself included). With the Smuggler's becoming a viable leveling area I felt indicating this would be a prudent action.
It used to be a one-way door back when I was a froob and as Masta said, you couldn't normally use it to go in the other direction. I never saw a patch note indicating it was changed so I never thought there was a faster way there.
