He wouldn't have had any choice. Lotus are the fastest cars when it comes to straight line speed and with DRS and KERS Kimi would've easily passed him had the race been one or two laps longer.
It was too late, though, and Lotus got their strategy wrong yet again. The only positives you can take from this is that, overall, Lotus have the quickest car on the grid and they have decent tyre degradation, not to mention great drivers. They're also the most consistent team, so even though they haven't won they're currently the ones accumulating the most points because both Kimi and Romain are finishing in the Top 5.
It's Lotus' strategy what's keeping them from winning a Grand Prix. In particular, Boullier's conformance with "only" wanting to be fourth in the Constructors' Championship and having two Top Ten (read: not Top 5) drivers. Clearly Kimi and Romain want to push and want to get great results, but Boullier's lack of aggressiveness and determination isn't helping the cause.
