PS Filter Caps / re-cap

Came across a board today which has two 4700uF / 50V Lytics and I noticed that I had to desolder THREE leads (per cap) instead of two! My best guess is that one of the lugs serves as a "support" so the Caps cannot bend on the board.

Any "other" ideas? I don't remember seeing a 3 lead cap before this BUT then again, this IS an old board, so that could be why!

Thanks

It's common, as are four tags - the others are quite rightly mechanical supports, sometimes they are isolated, but often connect to one of the other terminals (usually negative).
 
Metal can electrolytics commonly had two different caps in one package. They shared a common negative terminal.
