There are two thoughts on this that I have heard. One is like you say it may
appear the same from any direction you look at it. The thought being that
the ring look comes from there being a greater concenstration of matter
towards to edges (from our perspective or line of sight) as you are looking
though more matter.
The other one I have heard is that the Ring Neb turn sideways might look
like the Bug Neb which appears to have cone shaped extentions.
I guess unless we can actually go have a look then we'll really never know
