The reason for Seifert's Super Over role: the scoop and ramp shots which have become an accepted part of modern cricket.
Seifert's ability to play those made him the ideal candidate this time, according to Stead.
"We were pretty certain Chris Jordan would bowl and he is one of best yorker bowlers in the world," Stead said.
"Tim is probably the best guy in our team who can scoop and ramp, the idea being he would hopefully get the first one away.
"He tried but only got two. The aim was to take him (Jordan) off his length and make him bowl something different.
"Earlier in the day it was the slower balls which were getting hit out of the park. We needed to try some way of upsetting one of the best in the world at bowling yorkers."
The decision to bowl captain Tim Southee in the Super Over was down to Southee.
"Tim said 'I'm happy to do it' and put his hand up. You've got to trust people when they do that," Stead said.
