Splitting of a short exact sequence in cohomology due to torsion

Question

Consider a set $S$ of $n$ torsion points on an elliptic curve $E$, then I find in a paper a claim without any further comment, that the following short exact sequence splits, as a sequence of Mixed Hodge Structures: $$ 0 \rightarrow H^1(E,\mathbb{Q}) \rightarrow H^1(E\setminus S, \mathbb{Q}) \xrightarrow{Residue} (H^0(S,\mathbb{Q})(-1))^{deg \, 0} \rightarrow 0 $$ It would be very much appreciated if anyone has an idea why.
