Same thread was cut by using:
1. Collinear relation.
2. Pierce relation.
Is there any difference in cutting thread in different way?

they should produce same result (I've 2015, so couldn't open your file)
Pierce between point and helix - point will be coincident with the 'theoretical point' that is formed by intersection of helix with the cutting profile plane. Point is fixed, will not move.
Coincident between point and helix - Point can move along helix as long as the point is coincident with the projected helix on cutting profile plane. To fix the point another collinear constraint is evoked between vertical line and edge.
Check this awesome explanation by John Burrill on What is the difference between Pierce and Coincident relations in a sketch on coincidence and pierce relations.
Thanks
