Undocumented "Output" alignment argument to "Column?"

Question

In this SE question, Inheriting Stylesheets when using CreateDocument, I noticed the literal string argument "Output" to Column. I didn't see any documentation for this argument (see below), and I didn't see any effect of the argument:

and was curious what it does or doesn't do, or what it's supposed to do.

Silent documentation:

I think Column may be a very forgiving function with Options it does not understand. Try Column[{{1, 2, 3}, {3, 4, 5}}, "Harry"] or `Column[{{1, 2, 3}, {3, 4, 5}}, "Reb.Cabin"]'. — bill s, Apr 13 '16 at 17:55

It seems that it will align the column to the first character of the string you put there. So it's an undocumented extension to:

"c" - align on the character "c"

Column[{
  "OffOutputasodas",
  "OutputOffo",
  "adssoadasOffOutput"
  },
 "Output"
 ]

Column[{
  "OffOutputasodas",
  "oOutputOffo",
  "adssoadasOffOutput"
  },
 "output"
 ]
