I guess the general method is to keep cutting back the new tissue into new culture until you get tissue that doesn't show the problem, and then snip it one more time from the direction of the virus just to be safe.
In orchid tissue culture at least, you're right. Orchid tissue culture often uses the meristem, the newest growth of plants, which can sometimes grow more rapidly than a virus from the rest of the plant can infect the new tissue. So it's hoped that harvesting a little tissue from the meristem will produce virus-free plants in tissue culture.
In the case of "Spotty" the Venus Flytrap however, it is the characteristics that the (suspected) virus causes that are valued, the splotchiness in the color inside the traps, for example, so presumably one wouldn't want to get rid of the virus.
I'm personally very wary of plant viruses and wouldn't want to get a "Spotty" plant unless it were proved to be virus free with an experiment or virus testing.
