The 'Securing gas in foreign reservoirs' is going to get messy for everyone, all the countries are doing this, but when everyone is short of it (if there's a very cold winter with low wind) - what's going to happen? Some of those 'secure gas' isn't going to deliver.
The issue here is that Switzerland does not have any large gas storage in its borders and has for a while been paying other countries for storage. They need to make sure that gas still belongs to Switzerland when it comes down to the wire.
