Well, yes and no. The file you download using the .acsm file is an Adobe epub. The file you directly download is a Kobo kepub. The Kobo epubs use a double file extension of .kepub.epub to distinguish them from .epub files. The text inside the book is very likely the same but the renderer used to display kepubs is the ACCESS NetFront BookReader while the renderer used for .epubs is Adobe's Reader Mobile SDK. There are differences in how those two will display an ebook. I've seen epubs where I was happier with the formatting and kepubs where I was happier with the formatting.
