The second variant of the function evaluates whether the two input geometries
satisfy a specific spatial relationship defined by the provided
`intersectionMatrix` pattern.

!!!Note
It is important to note that this function is not optimized for use in
spatial join operations. Certain DE-9IM relationships can hold true for
geometries that do not intersect or are disjoint. As a result, it is
recommended to utilize other dedicated spatial functions specifically optimized
for spatial join processing.
