Unexpected lambda behavior C++ with Arduino

I'm trying to understand why the second millis() timer does not work as I would expect. Is there some encapsulation that I don't understand while using lambdas? Or maybe I'm just not seeing something!

the second expression in loop() does not print, the first does:

unsigned long timerVal = 0;
void setup() 
{
  Serial.begin(9600);
  Serial.println();
}
void loop() 
{
  [&timerVal](unsigned long currentTime){if(currentTime - timerVal > 1000UL) {Serial.println("Hello World"); timerVal += 1000UL;}}(millis());
  [&timerVal](){if(millis() - timerVal > 1000UL) {Serial.println("Why Not Me?"); timerVal += 1000UL;}};
}
