Hello Olivier, in fact, binding global variables is supported only in local mode, not in the server REST API.
The idea is that since the query is sent by the client, the values of global variables can be specified in the query itself. On the other hand, the XQS (XQuery Services) mechanism allows passing parameters to queries stored on the server side. Now, I agree that it should be documented somewhere, and perhaps display an error message.
