Electricity does not magically create gas for heating. Electricity in europe is primarily threatened by France failing to adequately maintain their nuclear power plants.
No, but when natural gas is 15% of your electrical generation, it does magically free up natural gas that would have otherwise been burnt for electricity.
More importantly: Gas-to-power. This summer, for some time we were using more gas than in previous years, because there was not enough wind blowing for power generation. Blackouts must be prevented, so we will use it for power generation if necessary.
