Trying to think creatively here, not that I think it would be true.
"Off" isn't always off - thinking of fruit tree buds that don't get the cumulative chilling hours required to break dormancy. Many of the flower buds still break dormancy, just not all at the same time.
So back to my original question, can you think of a mechanism where off wouldn't necessarily be off if it was present in multiple doses? Multiple copies of the gene might somehow interfere with normal function of the gene?
Maybe something like the petunia color genes that cancel each other out if they are "matching" sets, where one of either set is purple, but the two together result in white rather than darker purple (or pink or whatever color they were trying to intensify). 

<It is an off switch (need for vernalization is turned off)?
It doesn't matter how often it is turned off. Off is off. >
