There is no way to do so. Split screen in Android does not work in two browsers simultaneously, as it spends too much power. IOS itself doesn`t have that option.
However, you can follow two or even more matches at a time using, 365bet or https://777score.com/, for example. Of course, this is not a live translation, but it may be useful if you follow a lot of matches simultaneously while betting. The site provides enough variety of games from different championships. Enjoy!
