I’d like a clarification on how one makes use of Depots in Ticket to Ride.

Depots had been launched within the Europe 1912 Expansion pack. Here are the 2 guidelines that I’m questioning about. (Text, punctuation and formatting is from the printed English guidelines, numbering is mine for readability is that this query)

1. Each Time a participant makes use of his flip to Claim a Route right into a metropolis with a participant’s Depot in it, he could choose all of the Train playing cards from that participant’s Warehouse, by discarding one in all his personal Depots from his Warehouse again into the sport field.
2. Players could choose playing cards from their very own Warehouse, when claiming a Route right into a metropolis containing their very own Depot. And gamers could choose playing cards from 2 Warehouses in a single flip, when claiming a Route that connects 2 cities every with its personal Depot; to take action, they need to discard 2 of their very own Depots nevertheless.

Rule 1 is fairly clear however Rule 2 has me puzzled, why is the primary half even there? As I learn it fastidiously, it appears to me that the excellence in Rule 2 is that it’s your personal Depot and they don’t point out discarding a Depot out of your Warehouse “again into the sport field.”

Is {that a} right interpretation? For instance, if 2 gamers are taking part in, say blue and yellow. If the Yellow participant empties a Blue Depot it’s clear they need to discard one in all their Depots, but when they empty a Yellow Depot, can they keep away from discarding a Depot?
