I can't see any other option in this context. To answer your question, while score lines usually mean the tablet can be split, this is not always the case.
Take a recent Swiss study, for instance, which found that 2.7% of all scored tablets (and over 10% of hospital-only medicines supplied as scored tablets) should
not be split under any circumstances! In many of these cases, the scoring was purely decorative (a dangerous practice, if you ask me).

Here is an image of what I believe is the product your text refers to (shortened so as not to disclose the trade name). You can clearly see the tablets are scored in half on both sides. Cheers!
