There essentially the same thing. Although Jon I noticed on your diagram that although it does contain the second, it can't be called AMajSus2 OR AmSus2 because it has no third and thus no distinction between major or minor. I think the closest name you could give it would be A5(add2). This sometimes sounds really cool, but if I wanted to make it major or minor you could alter it slightly like so:


fret note steps from root
E |---0----------e-----()------------------|
B |---1----------c-----()------------------|
G |---4----------b-----()------------------|
D |---2----------e-----()------------------|
A |---0----------a-----()------------------|
E |----------------------------------------|

That would make it a true AmAdd9, and to make it major you would siply fret the second fret on the b string.
