Not in my opinion. I did some experiments with pasted hangers and a slightly arched bevel is no problem as long as the final angle stays in a normalish range. I believe one of the members here kept a journal in a thread of his multi-month-long experiment using a pasted strop, and noticed no degradation or dulling over that period.
But then neither is the praise heaped on the multi-bevel technique justified. This is a fine way to reduce the time spent on your finishing hone - this is after all why the commercial razor blade manufacturers use multiple bevels. But the resulting edge isn't any better or worse than you get using a single bevel.
