Subject: [PATCH 2/2] Remove duplicate code introduced in #440

#440 duplicated a block of code outside of `if (updateEnvironment) {` condition. This was probably an oversight when merging `main` back on the PR branch. The tests should have seen that `core.exportVariable` was being called and should have failed.
