Exercise 8 (6) on Lexical Semantics

In the last point, since we obtain D(S1,S2) > D(S1) and D(S1,S2) > D(S2), we conclude that the whole sentence (D1+D2) has a higher lexical cohesion, thus we don't split it? Is this reasoning correct? 

Thanks a lot in advance.

Hello,
I'd rather argue that you have to split it and your conclusions are erroneous.
In this case, we have a distance metric that we want to minimize, as a lower distance means that your text is more lexically coherent, which is the inverse of what you claim. Additionally, D(S1) + D(S2) < D(S1, S2), thus it's more beneficial to split it.
