BMM14 — Inconsistent use of romatting 'red' words (issue?)

Chapter 9.2 is a concept dictionary.
Some words are 'red' because they are keywords in structured English.
If you look into SBVR 1.4 documentation you can see that when there is 'red' word it has non-serif font.

If you look at definition 'business policy' in BMM 1.3 you can see that first word 'that' is written using serif font, but second 'and that' is written using non-serif font.
Others concept has 'red' words written using only serif font.

What version is correct? Serif or non-serif?
