Your diagnosis makes sense, since in PARI there are no multivariate
polynomials, only polys with poly coefficients.

The resultant of two homogeneous polynomials can return an incorrect
value:
R.=PolynomialRing(ZZ)
f=6*x^2 + x*y + y^2
g=y^2
print f.resultant(g)
m=matrix([[6,1,1,0],[0,6,1,1],[0,0,1,0],[0,0,0,1]])
m.determinant()
notice that the coefficient of the f.resultant(g) does not match the
integer determin
