To clarify what’s actually happening: The \etc makes LilyPond create a 
music function without you having to delve into the internals.

You need a music function instead of a simple variable because \after is 
a music function requiring three arguments. You want your \gruppetto 
function to still take one argument—the one that \after takes as its 
third argument—the actual note.

For more, see

(this is found by searching for \after in the LilyPond Command Index)
