What you have stumbled on there is the Luftwaffe's prototype self-destruct device that was later fitted to the V1. Bf109 pilots were given very clear directives to stop ramming Spitfires as the aluminium they were made from was recast pots and pans from Eastend housewives- nothing could touch them.....
On a more serious note: I haven't noticed that issue of 109's blowing up while Spits are unscathed. I'll have to note if it always occurs when the 109 touches them from behind- i've collided head on with a 109 and we both lost wings.
