Did I understand the idea behind subscription correctly:
The subscription represents a contract, defining e.g. payment terms, whereas the subscription lines define the service (which might change over the life-time of the contract).
Related: Is there a simplified view for subscriptions which will always hold a single line. (Example: 1 week test subscription for a newspaper.)

Mainly yes it is what is described in the documentation: [Sale Subscription Module — Tryton module for subscription](https://docs.tryton.org/projects/modules-sale-subscription/en/latest/#subscription)
