Delay by free-thrower after TO

[Nevadaref]

This came up at one of our meetings. Could someone please tell me why it is a violation to enter the free throw semi-circle if this is the correct player who is supposed to be shooting.
9-1-7 tells us it is a violation to cross the free throw line, but says nothing about entering the semi-circle.
10-3-7c clearly makes an exception to the T for delay when resuming-play procedure is in effect.
I just can't find anywhere in the rules where it is a violation to be late after a TO and come running in and take the merited free throw. I am talking only about the free throw shooter, not anyone coming in to a marked lane space.
Rules cite anyone?
