The price table is written against the catalog. The name reaching the
accountant was the one the caller typed, so every request made by an alias
missed the table and fell to the default price — the same request charged
two different rates depending on which of a model's names the client
happened to be given.
With no default price that is zero, which is silent. With one it is a wrong
number, which is worse: a budget spent at the rate of whatever the default
says rather than at the model's own.
The router already resolves the alias, two lines above, to decide whether
the key is allowed the model at all. It now passes the resolved name to the
accountant as well, in the ordinary path and in the budget fallback.
The test charges a real request through an aliased name and compares the
figure with arithmetic it states itself, because the first version of it
asserted "more than the fallback" and passed with the bug in place.
