With regard to Zephyr (or any other glass) being "soft", the viscosity of two different glasses at working temperatures is basically irrelevant regarding their compatibility with each other. I can formulate two glasses - one glass that's soft as warm butter at the same temperature where another is stiff as cold molasses, and still have them fit each other properly.
In the context of glass compatibility, the only viscosity that matters is where the strain point of the glass is, meaning the temperature at which a glass becomes stiff enough that whatever strain is in it at that point is permanently locked in at lower temperatures.
