Maybe, but this feels more like a protocol error to me.
It seems in this case the VAR has made the correct call, and quickly at that, and just gone "check complete" as a shorthand for "agree with your decision" which he erroneously thought was to allow the goal.
If instead they confirmed what the ref's decision was this wouldn't happen. "Check complete, goal is awarded". "Check complete, no penalty" then this sort of problem goes away.
