Description
The monomial cones in the decomposition come out not disjoint:
i1 : QQ[x,y,z]; standardPairs monomialIdeal(x*y^3*z, x*y^2*z^2)
2
o2 = {{1, {y, z}}, {1, {x, z}}, {y, {x, z}}, {1, {x, y}}, {y z, {x}}}
Here 1 is in three sets.

Research direction
Start by reproducing the standardPairs monomialIdeal example from the issue and inspect the standardPairs implementation or package entry point. Determine why the reported cones overlap, then add a regression test showing that the decomposition is pairwise disjoint and run the relevant Macaulay2 tests.
