Edge pointing to an edge? - orientdb

Question

In OrientDB 3.0.x (x>5) is it possible to have an edge, one of end of which is also an edge? It seems possible, but not explained in the docs:
--Define vertex A,B,C
create class testVertexA extends V;
create class testVertexB extends V;
create class testVertexC extends V;
--Define EdgeA that connects 2 vertexes -A and B
create class testEdgeA extends E;
create property testEdgeA.in link testVertexA;
create property testEdgeA.out link testVertexB;
--Define EdgeB that connects EdgeA and vertex C - is this possible?
create class testEdgeB extends E;
create property testEdgeB.in link testVertexC;
create property testEdgeB.out link testEdgeA;
Next, we put in some data, to see if this works at all:
orientdb > insert into testVertexA;
Inserted record '[testVertexA#225:0 v1]' in 0.000000 sec(s).
orientdb > insert into testVertexB;
Inserted record '[testVertexB#233:0 v1]' in 0.016000 sec(s).
orientdb > insert into testVertexC;
Inserted record '[testVertexC#241:0 v1]' in 0.000000 sec(s).
orientdb > insert into testEdgeA set in=#225:0, out=#233:0;
Inserted record '[testEdgeA#249:0{in:#225:0,out:#233:0} v1]' in 0.000000 sec(s).
orientdb > insert into testEdgeB set in=#241:0, out=#249:0;
Inserted record '[testEdgeB#257:0{in:#241:0,out:#249:0} v1]' in 0.000000 sec(s).
orientdb > select from testEdgeB;

Can someone affirm this . Thanks
