This seems like claiming that a pizza place and a taco place aren't competing because they're completely different experiences - I'm still only going to eat one lunch, and I'm only going to use one service for lodging overnight somewhere

They're definitely serving a market with only partial overlap. E.g. I personally am in a market for pizza, but not for tacos.

Well, just for the two you, they have combination Pizza Hut and Taco Bell restaurants, so you can have a choice of pizza and/or tacos, depending on what you feel like eating at that exact moment!
