[1] A regular break for rest or to eat meals does not count as a "split".
This kind of pattern is especially common for people such as public transport employees (where it is advantageous to have additional staff working during traditional rush hour times) or bar staff that work at lunchtimes and during the evening.
People working split shifts are just as likely to be men or women, and equally likely to be parents of small children.
