Just think dry sack vs compression sack, kind of the same but not really. It's all right. I'm just gonna take it and exchange it tomorrow for something more like the REI one.
Ah, the one you linked to:

is exactly like what we have, with 4 straps. Works like a charm. Only the bottom is the eVent fabric. The air goes out the bottom when you pull the straps, so no air is trapped. Totally compressible and easy to do. Maybe what you have is not what you linked to.
