For some reason I have a mental block about how intersection works. Union is OK; I can see that

set a; set b; bloom_filter(a) union bloom_filter(b) == bloom_filter( a union b );

but it's not clear to me if

bloom_filter(a) intersect bloom_filter(b) == bloom_filter( a intersect b );

Can you convince me?

That is correct, afaik only union (or) and difference (xor) can be applied to non-counting BFs.
