Morphology
The phrase is directly compositional: 'mutual' (reciprocal/shared between parties) combined with 'exclusiveness' (the quality of excluding others) yields the idea that the items reciprocally exclude one another. This follows a regular adjectival+noun composition and is cross-linguistically common, so a B1 learner who knows the constituents can infer the meaning.
Etymology
Mutual exclusiveness shows a clear picture: mutual means 'each other' and exclusiveness means 'only one', like two light switches connected so when one is on the other must be off. So, it means that two or more things 'cannot both be true' or 'cannot happen at the same time'.
