onPressIn getting called twice if view moves - react-native

Question

I created a sort of demo on expo: https://snack.expo.io/#noitsnack/onpressin-twice
I tested this by scanning QR code in expo. This may be a expo bug.
I have wraped the expo symbol (an <Image>) in a <TouchableWithoutFeedback>. Here we see that when we press the expo symbol it causes the score to increase by one, and then the symbol moves to a new location. Sometimes it causes the onPressIn to trigger twice. I don't understand this, why does this happen?
Here is the code to the expo:
import React, { Component } from 'react';
import { Text, View, TouchableWithoutFeedback, Image, Dimensions } from 'react-native';
import IMAGE_EXPO from './assets/expo.symbol.white.png'
const IMAGE_SIZE = 100;
export default class App extends Component {
state = {
score: 0,
...getRandXY()
}
render() {
const { score, x, y } = this.state;
return (
<View style={{flex:1, backgroundColor:'steelblue' }}>
<Text style={{fontSize:72, textAlign:'center'}}>{score}</Text>
<TouchableWithoutFeedback onPressIn={this.addScore}>
<Image source={IMAGE_EXPO} style={{ width:IMAGE_SIZE, height:IMAGE_SIZE, left:x, top:y, position:'absolute' }} />
</TouchableWithoutFeedback>
</View>
)
}
addScore = e => {
this.setState(({ score }) => ({ score:score+1, ...getRandXY() }));
}
}
function getRandXY() {
return {
x: getRandInt(0, Dimensions.get('window').width - IMAGE_SIZE),
y: getRandInt(0, Dimensions.get('window').height - IMAGE_SIZE)
}
}
function getRandInt(min, max)
{
return Math.floor(Math.random()*(max-min+1)+min);
}
