That's absolutely fair, and I do think some of the elements could suggest Gou...going solo later on, but people recently were complaining about Ash not being shown wanting to...travel enough for some reason, and this episode at the very least should quell those complaints for a bit (though I was largely fine with Ash here).Satoshi wasn't neeeded at all.
They could've made Tsurugi save Gou instead of having Satoshi's attempt dragging the scene.
It'd be more impactful.
Barring that, it was a good episode.
