Grammatical remarks seem to ask for expression in the present tense. But suppose you want to make grammatical remarks about, say, watching television. What we say about watching television, and what we mean by what we say. A present tense remark would fail to acknowledge that television's moment has passed, that that's not how it works, that's not what we (have to) do. A past tense remark renders it too distant, makes it seem as if history is being recounted, while somehow omitting the particular kinds of historically contingent necessities one means to call attention to in making grammatical remarks.
