There is a difference between keeping a lens with fungus on a shelf next to some other lenses and keeping it in a camera bag with other lenses. In an more enclosed space, particularly one that already encourages the growth of fungus, the spores which are produced by the infected lens will be of a higher concentration and so it will be more likely the other lenses become infected.
Just like you are more likely to contract a cold when you spend all day sitting next to a guy who has a cold in a crowded classroom, as opposed to sitting next to the same guy on a park bench with the wind blowing.
Please see what I wrote about this in the thread.
I no longer want to take part in any fungus infection discussion, I have said everything about it from my side
