You can touch the abdomen in the IPF now too - it just can't touch the belt, so easy, don't wear one. Apparently it was too hard to judge where someone's chest is because every person's sternum differs. The only real difference between IPF and other feds is head on bench and heels on floor.
And Sticky is right. There is no "pause" rule. The bar must be motionless before the ref gives the press call.
I do think this was touch and go but I've seen the similarly generous calls in the IPF. It happens. Lifter's luck.
