plural key vs mnemonic tag for plural categories

[jpnjfk-sas]

Let me confirm if the plural key corresponds to the mnemonic tag for plural categories.
For example,

.match {$count :plural}
[one] {{You have one notification.}}
[few] {{You have few notifications.}}
[many] {{You have many notifications.}}
[ *] {{You have {$count} notifications.}}

The one, few, and many in the complex-message above correspond to pluralRule-count-one, pluralRule-count-few, pluralRule-count-many respectively defined in the file?
That means the meaning of one, few, and many depends on the locale.

Yes, the meanings of the CLDR plural category keywords are locale-dependent.

Thank you for clarifying that!!
