If you all look at that reply of Lewis correcting himself again it is clear Di resta ended up with more room than if lewis hadn't corrected himself and just stayed there.
Yup, thats the thing that makes it insane, he wasn't off the track and came back on and spun himself around dangerously, he was in an insanely dangerous position and frankly the safest course of action was getting out the way as quickly as possible. He could have gone forwards a bit more but, if you spin and hit the grass with the back end, he could have spun completely out of control anywhere on the track again. Had he edged forwards a bit, one of the cars coming could have decided to go to the left side where he was moving, and still hit him.
The only safe action was get the heck out the way asap, thats what he did.
As for the race, meh, something strikes me as wrong as Button pitted first, but had better tyres and more pace than Hamilton frequently which simply, honestly, doesn't happen. Did he burn his tyres out by overdriving, then why did his supersofts end up slower than the softs as soon as Button after a lap, there was just a lack of pace, maybe a slightly different setup, Hamilton set for more downforce and more wet, and Button set for more speed and less downforce?
If Alonso had stopped going off the track no idea really if he had the pace to stay up the front, the RBR's simply didn't have enough race pace.
Hamilton got very unlucky to essentially be the first fast man through that chicane in one lap of rain, no one else infront of him pushes the corners as hard(ie much slower backmarkers) and most of the people behind him had a chance to be warned. Without that the soft/supersoft pit probably cost him 1st but he should have had 2nd with ease.
Why on earth they gave him wets rather than wait one more lap and see how Webber was doing on his I don't know, another crucial and ridiculous error by Hamilton's strategy guys. The penalty, is just a shockingly poor decision topped by many other shockingly poor decisions that do seem to very unfairly focus on Hamilton.
Should have been a Mclaren 1-2 either way, two massive pitstop errors by Mclaren costing Hamilton a easy podium.
