Hyper Linguist trait and character advancement

I have a character with the Hyper Linguist positive trait, ready to advance with rez points and interested in learning languages they don't know.

However, I've got the feeling the description of the trait doesn't fit in the rules for character advancement.

The text of the Hyper Linguist trait in the Core Rulebook (p.146) reads as follows:

The character has an intuitive understanding of linguistic structures that facilitates learning new languages easily. The character requires one-third the normal amount of time and experience to learn any language. The character can also learn any human language in one day simply by constant immersive exposure to it. Additionally, the character receives a +10 modifier when attempting to interpret languages they don’t know.

The description of the Language skill (of the Knowledge category) in the Core Rulebook (p. 181) says:

A speaker is considered fluent at a skill level of 50; anything above this indicates further refinement in technical vocabulary, accents, and knowledge of dialects.

In the Character Advancement section of the Core Rulebook (p. 152), "Improving Skills" describes how to increase Knowledge skills:

In the case of Knowledge skills, this means actively studying. As a rough timeframe, this should require around 1 week of learning per skill point.

The way I understand this, in order to become fluent in any language, a character with the Hyper Linguist trait would need to spend 17 rez points and 17 weeks of study (one-third of 50, rounded up).

But if the language is a "human" language (e.g. French?), the same character could "learn" it (become fluent? Get the 50 skill points in that language?) with one day of exposure, without spending any rez points.

Is this a correct interpretation of the rules? If not, what is the correct way to use the rules?
