Weird behavior using step

gistfile1.txt

		var nouvelle_conn;
	        Step(
	        	function ha2() {
	    			if (client._path != null) {
	    				nouvelle_conn = tcp.createConnection(client._path);
	    			} else {
	    				nouvelle_conn = tcp.createConnection(client._port, client._host);
	    			}
	    			var self = this;
	    			sys.puts('end of ha 2');
		                nouvelle_conn.on('connect', function() {
		                	nouvelle_conn.on('data', self);
		                });
	        	},
	        	function ha3(err, d2, data) {
	            	nouvelle_conn.removeAllListeners('data');
	    			nouvelle_conn.setNoDelay(true);
					var decoder = data.toReader();
	                status  = decoder.int16();
	                version = decoder.int16();
	                len  = decoder.int32();

	                console.log('connection to server version ' + version);
	                if (version < 1) {
	                	err = new Error("Invalid Server version");
	                	throw(err);
	                }
					var version_number = Buffer.makeWriter();
					version_number.push.int32(1);
	                nouvelle_conn.write(version_number.toBuffer(), '', this);
	    			sys.puts('end of ha 3');
	        	},
	        	function ha4() {
	                sys.puts('_connect: ' + sys.inspect(nouvelle_conn));

	    			sys.puts('end of ha 4');
	    			return;
	            }
	        );
	        sys.puts('out of step, at least');					
		

Here is the output I get - the 'obj [object Object]' line is from the calling function:

end of ha 2
out of step, at least
'obj [object Object]'
