what for max() function?

[mistepien]

Why in library max() function is used

word SegaController::getState() { if (max(millis() - _lastReadTime, 0) < SC_READ_DELAY_MS)

instead of

word SegaController::getState() { if ((millis() - _lastReadTime) < SC_READ_DELAY_MS) {

What is a gain of using max() function?

I think when I wrote this I just didn't realize it'd still work with the overflow wraparound.
