The docs go on to say that 'virtualedit' changes what happens:
When 'virtualedit' is used {expr} can be [lnum, col, off], where
"off" is the offset in screen columns from the start of the
character. E.g., a position within a <Tab> or after the last
character. When "off" is omitted zero is used.
I added the last sentence to make clear what happens in your situation.
