Not necessarily both live all of the time. In the case of more complex light switching (with multi-gang switches), one might need to know which of a pair was the 'permanent live'.Why does it matter ? 2 browns as either may be live.

Yes, if you use twin brown cable for the 'strappers' between two switches in a 2-way switching set up, then it doesn't make any difference which is which. However, as I said, in some other light switching situations you might need to know which of two browns in a 'switch drop' was the permanent live.When I have wired 2 switches to control one light. on off from either switch - hall to landing etc either wire can be live. That's why it was introduced. Before L & N was used - ok if you know it's that style of circuit.
There you go.not normally necessary except where you need to identify permanent phase
