The short answer is yes. In some of the more well conceived versions of these pants, and pants that are related, like Helmut Lang's pants from the 1990s with straps between the legs, there were/are implicit or explicit invoking of bondage and BDSM. So, movement was explicitly impeded. A lot of the designers that do it now, I can't be sure whether it's that well thought out. I imagine that in some cases it is, and that in orders, it's as simple as "Oh, that might look cool, bro."
