I'm talking about the procedure generally (which also mirrors my own). Of course, practices will vary, but in answering a general question we can't account for all possibilities. If people are overly concerned wit this, they'd need to discuss it with their surgeon.
Having said that, I think I'm right in thinking that in natural, non-transplanted hairlines, there will be a mixing singles, doubles etc (but singles dominate), so the odd triple in the hairline shouldn't look too bad, so long as there are mostly singles.
