Yep the split is the same but the conversions back to your base currency that can be a bit of a faff, especially if we're on holiday and doing these calculations multiple times per day

For example if I go to a restaurant with a large group and each item on the bill is in yen, we need to sum each person's total in yen and then convert each of their totals into GBP so we can each transfer what we owe (easy enough)

But depending on the exchange rates and rounding, those calculations can sometimes be off by a penny or two. Some people don't mind, others do
