Yes, here it's telling the sender to get to the provided node, then ask it to use that channel. The channel is using an alias, because it's not public, but that node will know which one you're talking about. Then, the sender can compute the route and factor in how much this peer charges to use this channel.

Your node can add multiple of these hints and each hint can even have multiple hops. It should be smart enough to figure out which hints it needs depending on the size of the payment and how much inbound liquidity you need.
