It really does matter.
Glossaries are especially important during translation. Word lists, databases and guides also help us to agree on the meaning of specific words and phrases. Adopting a standardised reference tool can not only help to avoid misunderstandings but also ensure consistency and thus coherence and good branding across your organisation.
