Internally, there is actually no notion of the mark not being set ---
it's simply initialised to zero, and moved when ask it to be set.
Therefore, if you try and use it, it appears as if it's at the start of
the line.

The documentation doesn't make this explicit.  It could do with
mentioning the default state.
