New laws which came into effect on 1 June and were outlined by the International Football Association Board (Ifab) , external mean a penalty kick can be retaken if goalkeepers are spotted advancing.
Scotland goalkeeper Lee Alexander saved a late penalty in her side’s 3-3 draw with Argentina but a retake was ordered after VAR ruled she had moved off her line before the kick was taken.
The retake was scored and Alexander became one of three players booked for encroachment during the tournament so far.
France also benefited in a group game when a penalty against Nigeria hit the post.
VAR determined that Nigeria keeper Chiamaka Nnadozie had moved off her line early and Wendie Renard scored the winner from the second spot-kick.
Italy scored their first goal in a 5-0 win over Jamaica with a retaken penalty after goalkeeper Sydney Schneider was punished for moving off her line in saving the initial spot-kick.
The decisions were correct according to the new laws, although Fifa has since said goalkeepers will not be booked if they break the rule during a shootout.
Collina said football’s law-makers had changed the rule to help goalkeepers by allowing them to just have one foot on or level with the line rather than two.
“We acknowledged that saving a penalty by keeping two feet on the goalline until the taker kicks the ball makes the goalkeeper’s job almost impossible,” he added.
“If something is written in the laws of the game it must be respected.
“It is not a matter of a small encroachment or big encroachment, it is a matter of encroachment, and this is what we can do by using technology.”
England boss Phil Neville said this Fifa had “major decisions to make” over the use of VAR after controversy around decisions dominated the group stage, while Manchester United Women manager Casey Stoney said it was “ruining the game”.
