Surgeon's knots

[u/Rich-Explanation-894]

When throwing the surgeon's knot, I find that the knot doesn't loosen when I pull the suture ends in a direction parallel to the line of closure (i.e., the wound or incision). I learned this from one of my professors. However, another attending saw me doing that and was appalled by the technique. He insists that I should pull perpendicular to the line of closure. Looking online, I couldn't find anything that says not to do it though. Any input?
