If you store the squeeze bottle on the business end, as intended, then all the runny liquid will go to the top. It's only when you store it with the nozzle up that it's an issue. This is one of the reasons for the pressure nozzle everyone loves to hate.
Personally, I pour the ketchup into a generic food service squeeze bottle. It requires shaking before use to reincorporate the separated liquid, but it's generally a lot easier to use than either of the squeeze-top designs Heinz has. Far better control over the rate of ketchup coming out than either of the others.
Given the pandemic-induced shortage of ketchup packets, it's not surprising to see a gadget designed to get out every last drop.
Of course, this story needs to be paired with the one about the technique of opening the packet so you can dip your fries directly into the packet. I don't think that would work for me since I typically use half a dozen packets on a single serving of fries. Fries are nothing but a ketchup delivery medium.
