Let's help make the code clearer by posting it correctly so that it is easier to read

int threshold = 60;
bool touchdetected5 = false;
bool touchdetected4 = false;
const byte led_gpio1 = 32;
const byte led_gpio2 = 33;
const byte led_gpio3 = 36;

int value = 0;
volatile unsigned long sinceLastTouch5 = 0;
volatile unsigned long sinceLastTouch4 = 0;

void gotTouch5()
{
  if (millis() - sinceLastTouch5 < 500) return;
  sinceLastTouch5 = millis();
  touchdetected5 = true;
}

void gotTouch4()
{
  if (millis() - sinceLastTouch4 < 500) return;
  sinceLastTouch4 = millis();
  touchdetected4 = true;
}

void setup()
{
  Serial.begin(115200);
  pinMode(led_gpio1, OUTPUT);
  pinMode(led_gpio2, OUTPUT);
  pinMode(led_gpio3, OUTPUT);
  delay(1000); // give me time to bring up serial monitor
  printf("\n ESP32 Touch Interrupt Test\n");
  touchAttachInterrupt(T5, gotTouch5, threshold); // T0 = GPIO 4
  touchAttachInterrupt(T4, gotTouch4, threshold); // T3 = GPIO 15
}

void loop()
{
  if (touchdetected4 && touchdetected5)
  {
    touchdetected5 = false;
    touchdetected4 = false;
    digitalWrite(led_gpio3, HIGH);
    delay(150);
    digitalWrite(led_gpio3, LOW);
    delay(150);
    Serial.print("Both Teouched - Value: ");
    Serial.println(value = value - 1);
  }
  if (touchdetected5)
  {
    touchdetected5 = false;
    digitalWrite(led_gpio1, HIGH);
    delay(150);
    digitalWrite(led_gpio1, LOW);
    delay(150);
    Serial.print("Touch 5 detected - Value: ");
    Serial.println(value = value - 1);
  }
  if (touchdetected4)
  {
    touchdetected4 = false;
    digitalWrite(led_gpio2, HIGH);
    delay(150);
    digitalWrite(led_gpio2, LOW);
    delay(150);
    Serial.print("Touch 4 detected - Value: ");
    Serial.println(value = value + 1);
  }
