Where the article explains it

If workers i and j each have mutation set $W_i$ and $W_j$ , then filesystem isolation addresses $W_i^{\mathrm{files}}$ $\cap$ $W_j^{\mathrm{files}}$ but not intersections across external services.

The passage around this formula

Race risk grows with shared mutable resources. If workers i and j each have mutation set $W_i$ and $W_j$ , then filesystem isolation addresses $W_i^{\mathrm{files}}$ $\cap$ $W_j^{\mathrm{files}}$ but not intersections across external services.
