That's the case when the readback is incorrect or missing, i.e. the pilot heard something that wasn't said. In this case, the instruction was communicated correctly on both ends. But it wasn't followed correctly.
Someone saying the exact same words back to you doesn’t prevent miscommunication. If the pilot and ATC had the same understanding of the situation then the pilot wouldn’t have done something likely to result in a crash.
If they have the correctly communicated instructions as you imply, then why weren't they followed? Is it not also possible they don't follow the red light if they think ATC instructed them to use that runway?
Hard to say at this stage, but initial impressions seem to be that the pilot was following the instructions but were mistaken about what was in front of them.
