BTN_STATE_REPEAT 状态疑问

[crazy3min]

case BTN_STATE_REPEAT:
		if (handle->button_level != handle->active_level) {
			// Button released
			handle->event = (uint8_t)BTN_PRESS_UP;
			EVENT_CB(BTN_PRESS_UP);
			if (handle->ticks < SHORT_TICKS) {
				handle->ticks = 0;
				handle->state = BTN_STATE_RELEASE;  // Continue waiting for more presses
			} else {
				handle->state = BTN_STATE_IDLE;  // End of sequence
			}
		} else if (handle->ticks > SHORT_TICKS) {
			// Held down too long, treat as normal press
			handle->state = BTN_STATE_PRESS;
		}
		break;

重复按下，状态，按键重新释放，这个条件 if (handle->ticks < SHORT_TICKS) 是否多余？ 要么按键持续按下超过 SHORT_TICKS 转换状态。要么在 SHORT_TICKS 内释放按键

请问是什么情况下需要处理这种情况？如果不处理是有异常？ handle->ticks == SHORT_TICKS)
