What whitemeat describes is what we do when the follower becomes the leader for the next pitch (switching leads at the anchor). It is simple, efficient, and safe.
However my question was related to the case when the leader leads in blocks (i.e. the previous leader leads the next pitch). How should the follower attach to the anchor so that the anchor would be safe even if the leader takes a Factor 2 fall on the anchor?

Swap ends of the rope, triple checking your tethers/daisies/knots before and after the high-G maneuver?
...even if the leader takes a Factor 2 fall on the anchor?
Don't. Redirect the rope through a draw on a bolt, there will be enough extra rope between the belayer and that draw to greatly reduce the fall factor, and the belayer will go for a small ride to further reduce the impact. Am I missing something?
Hudon's setup does not create a nice obvious "Power Point" like a cordelette, but instead uses squishy rope on (hopefully) bomber bolts to be good enough. The follower gets 2 semi-equalized bolts to jug on, but the belayer is hanging off of one clove, backed up to the other bolts. With good bolts this is just fine with me.
I am however not a fan of hauling off of 1-bolt, it weirds me out, especially with a static haul line. Nothing about his main haul anchor precludes hauling off of a sliding-X or knotted sling to put some redundancy into the haul anchor. He ties all the bolts together so you wonld not lose the pig entirely, but there could be quite the mess if the haul bolt popped and the whole rig dropped a couple feet.
