That's not why. Gas turbine engines utilize control systems that monitor speeds, temperatures, pressures, fuel flows, vibrations, etc to run the engine as close to its physical limits as possible. Bleed air can be a contributing factor via cooling to the turbine blades, but it is not the reason "jet engines don't melt themselves".
