The U.S. Constitution refers to "the several States" in various places (e.g., Article I, Section 2).
Under U.S. law, therefore, several can mean 13 (the original number of states) or possibly 50 (the current number).

It's likely that modern interpretation extends the intent to the obvious meaning 'the collection of States (that are part of the country)'. More modern math and logic terms might not have been in wide use at the time, and a 'group' of states sounds inherently ill defined. 'The States of the United States' just sounds silly.
For example, contracts concluded between multiple parties often include terminology like “jointly and severally”.
The term “several” shares its roots with “sever”, and means essentially “unlinked”.
