Look at it this way, I personally feel a lot of the reforms do answer many negatives 'Brexiters' (Some, not all), have about EU membership, so if the result is one that we stay in, the EU needs to vote in favour of the reforms, such as no further integration, British regain control over it's border policies, never joining the Euro single currency, no involvement with an EU Army etc, in order to ensure Britain does remain a happy member. If the EU refuses the reforms, or only accepts some of them, I can see a justified arguement for a second referendum in the very near future. For (most) Brexiters, it's a win-win in that sense although for many it'd still be a case of "it's a start...".
