No. See the note in Wei's description about this:

> Note that this patch only changes the distributed thinlto mode. For in process thinlto mode, one source module is shared across different thinlto backend threads so it is not changed in this patch.

Specifically, for in-process ThinLTO all modules are kept open so that we don't need to reload a module for each thread that wants to import from it.
