Possibly wrong word used in the sentence about parallelization that build systems do

[Andrei Cheremskoy]

In the 1st part where the driver calls a number of compilers to compile source code for 3 languages it says:

The driver ran all the steps sequentially but build systems leverage this translation unit isolation to drastically reduce their wall-time duration. They purposely avoid using the driver to spawn multiple compilers to turn source files into objects in parallel.

It seems to me the intention was:

The driver ran all the steps sequentially but build systems leverage this translation unit isolation to drastically reduce their wall-time duration. They purposely avoid using the driver to spawn multiple compilers to turn source files into objects in parallel.

It was clarified that the sentence below is correct.

The driver ran all the steps sequentially but build systems leverage this translation unit isolation to drastically reduce their wall-time duration. They purposely avoid using the driver to spawn multiple compilers to turn source files into objects in parallel.
