tcm run gives what it runs the codebase's commands (<COMMAND>_BIN), but one the caller set is kept, and said: an end-to-end test run against another build (TCM_BIN=<tcm.js> tcm run <test>). One a tcm run further out set (TCM_COMMANDS), the build as it was then, is replaced, as is one of the codebase's own runners (a tcm run further out made it, though a tcm from before TCM_COMMANDS doesn't say so).
