Other references I found said it could also be used for cleaning the pipeline (introducing and removing solutions I believe) and pressure testing with some instrumentation actually inside the startup head pipes. It's accessible by ROV for those procedures.
Maybe startup head was a misnomer in the video since it seemed to be only at the end of the pipe laying process; or, perhaps it's commonly called that in practice at either end.
