This field has regexp constraint, to make satis.json compatible with upcomming changes in composer itself. Basically You could enter any string, but then satis would throw some unwanted deprecation warnings like this:
Deprecation warning: Your package name Composer repository is invalid, it should have a vendor name, a forward slash, and a package name. The vendor and package name can be words separated by -, . or _. The complete name should match "[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9]([_.-]?[a-z0-9]+)*". Make sure you fix this as Composer 2.0 will error.

So it is not a bug.
