When a member is offset from its reference node, a rigid link is created between the original node which is unmodofied and the new member end position. The link is essentially a very stiff member with both ends fixed. If the member in Ram Elements is then hinged, the hinge occurs at the new end location of the member, before the rigid link.
Note, other Bentley Structural Analysis and Design products like STAAD.pro and RAM Structural System are similar in this regard.
