No, it is for all the @-commands, and, in my opinion, the sentence is clear as is.

I think it is indeed italics, but my point was that the font in math is slanted (italics is slanted), which seemed similar enough to the effect of @var in the main text (which is also slanted, though not with a 'cursive' style), that I chosed not to change anything else. > There is another issue: math mode > disables kerning (because a sequence of letters typically means that > this is a product), unless some command is used to specify that this > is actually text.

We try to avoid ligatures in math mode. -- Pat
