Nothing is wrong with it, and many of us do that.
A hanging stand is more of a practical/aesthetical way of storage, and not a more functional or "better" method.
There's a lot of argument this way and that about it, but even the best arguments boil down to an opinion (and most pro-hanging opinions are related to the strength of the knot inside the handle)..
Standing your brush is perfectly fine, and is not detrimental to its life or how well it functions. And like the instructions for your brush, most others also recommend standing them. The only thing you could do wrong is to store a soaking wet brush in an enclosed container for a long period of time - hanging OR standing.
Hope that helps.
