In vi if you move the cursor up or down rows your column position will be maintained. If you move to a row with fewer characters than your original column position the cursor will move to the end of the line, but if you then move to another line long enough to have your original column position the cursor will move to that column.
I.e. if you were working on the following 4 line document and your cursor started at the capital X, as you moved down your cursor would be at column 3, 2, 1, and finally 3 on the last line.
Without Vintage enabled Sublime has the same behavior. But when Vintage is enabled your cursor position is 3,2,1,1 when scrolling through the same document. I.e. a a short line resets the saved column position to the length of that line.
Another user mentioned this in a forum post on a different topic (link below), I wanted to start a separate post to ensure this was tracked as an issue.
