I think it wouldn't hurt to add comments to spell it out explicitly
in each of the tsk->me functions, something like:

/*
 * The "me" task_struct argument here must only ever refer to "current",
 * but it gets passed in to avoid re-calculating "current" in each helper.
 */

I've found that the exec code in its entirety would be better off with
more comments. :) Usually that's the bulk of what I find myself adding
when I make changes in this area. ;)
