Ah, you will be fine.
Now if the garment is really really suseptable to sublimating. Then you can see some dye migration at those points... but not to much.
What you will typically find though, is the printer does not like how the print looks with the small fibers popping through, and go's back and fixes the print, fixing the minor potential for bleed.
Those threads that pop through are cotton, not polyester. Which is why you typically do not have a problem.
