Player location during technical foul free-throw

[David]

In NF Rule 8-1-5 it says "Any player, other than the free thrower, who does not occupy a marked lane space must be behind the free-throw line extended and behind the three-point line."

Does this rule apply to player location during a technical foul free-throw? Is it just tradition in Texas when we make all the players but the shooter go to the division line?
