Understanding ICP20100 baro driver ardupilot code

General
1

I’m reading ardupilot code and writing a test code for my hardware, but I see icp20100 driver tries read ID and Version for once and when it fails, there is no retry. I’m curious why since my test code tested a pass and ardupilot tested a fail.
btw my hardware fails for the first read and then passes on the second read and so on.

bool AP_Baro_ICP201XX::init()
{
    if (!dev) {
        return false;
    }

    dev->get_semaphore()->take_blocking();

    uint8_t id = 0xFF;
    uint8_t ver = 0xFF;
    read_reg(REG_DEVICE_ID, &id);
    read_reg(REG_DEVICE_ID, &id);
    read_reg(REG_VERSION, &ver);

    if (id != ICP201XX_ID) {
        goto failed;
    }

    if (ver != 0x00 && ver != 0xB2) {
        goto failed;
    }

    hal.scheduler->delay(10);

    soft_reset();
