During a run, after you finish a column, what happens when you roll it again? Do you bust?

I never made sure about this, but I imagine after you reach the top of a column and you continue to roll (for some reason, perhaps because you still have dice, or you have to win before the opponent plays), what happens when you roll the number of that column? Do you bust like it was a column completed previously? Does this column become immediately out of bounds lets say? I am 99% sure but yeah...

Winning a Column
...
b) You may not place a marker into a column that someone has already won--even if you’ve won that column yourself.
Example: Let’s say that columns "6", "8" and "10" are already won, and you roll a 2-4-4-6. You’ve "blown it"-- even if you still have markers to place.

Edit: actually, it's the segment right above it.

a) A marker on the number at the top of a column does not mean you’ve won that column.
Example: Let’s say you’ve placed markers into columns "3", "6" and "8", and that you’ve just moved the marker in column "6" to the number at the top. You could stop your turn now and win that column by replacing each of the markers with one of your colored squares. You decide, however, to roll again -- hoping to win columns "3" and "8", too. You roll a 2-4-5-5. Tough luck. You have no more markers to place, and you can’t move the marker in column "6" any higher than it already is. So you’ve "blown it" and must end your turn by removing all of the markers that you’ve placed. In other words, you do not win column "6".

That’s not the answer to the question.

Say I’m rolling and I get to the top of the 8s, but I still have a marker left. I haven’t won the 8s yet. I roll 4 4’s. Do I bust? I technically have not yet won the 8s, and I’ll be losing them with a bust anyway. Is it a bust or just reroll?
