and I would paraphrase like this:
An FI shall have his/her privileges limited to conducting flight instruction ....in the following cases:
I would agree with you if the FCL wording was "An FI shall have his/her privileges limited .....
to the following cases:" but the preposition used is
in not
to
Another point in the favour of my understanding:
FCL.905.FI FI—Privileges and conditions
The privileges of an FI are to conduct flight instruction for the issue, revalidation or renewal of:
(a) a PPL, SPL, BPL and LAPL in the appropriate aircraft category;
(...)
(e) the night rating, provided that the FI:
(1) is qualified to fly at night in the appropriate aircraft category;
(2) has demonstrated the ability to instruct at night to an FI qualified in accordance with (i) below; and
(3) complies with the night experience requirement of FCL.060(b)(2);
(...)
(g) an IR in the appropriate aircraft category, provided that the FI has: etc.
You certainly agree that a FI restricted may instruct for the night rating. The night rating is not treated differently than the IRI in the FCL. It's not written that the FI may be restricted to instruct for the night rating, nor is it written that the FI may be restricted to instruct for the IR, because IR and night are not in the FCL.910.FI list of restrictions
