I'm not sure that this is what you are referring to, but I have tried bottling force carbed soda into glass bottles. It did not work well.
I made a rootbeer with sugar, water and a flavor kit, then force carbed it in a keg to about 50 psi. To serve it, I had to take the pressure down to about 8 PSI and I used about 10' of 3/16" beverage tubing. The rootbeer tasted fine, but always seemed to foam too much when serving and came out flat.
I tried bottling it in glass beer bottles using a Mr. Beer gun. I had to take the pressure down to about 2 PSI or else I got all foam. Even with 2 PSI, I got a lot of foam and the bottles only ended up about 3/4 full when the foam settled. After capping and waiting a week I had rootbeer syrup in a bottle with not much carbonation at all. A true counter-pressure filler might work better for soda than a Mr. Beer gun, but I haven't tried.
