Yes. They are offset by a fixed distance **on the screen**, defined by
opt_dx and opt_dy (see below).

Look in the documentation:
// Create the offsetable marker
//
// GLatLng - mkrPoint the actual position to be marked
// GMarkerOptions - mkrOpts the options for the marker
// opt_color - color string for the offset line e.g. "#FF0000" or ""
to use the map's default text color
// opt_width - width for the offset line in pixels
// opt_opacity - opacity for the offset line, 0.0 (transparent) to 1.0
(opaque)
// opt_dx - x pixel offset for symbol, the same at all zooms
// opt_yx - y pixel offset for symbol, the same at all zooms
//

// Events dragstart, drag, dragend and dblclick used internally

function OffsetableMarker(mkrPoint, mkrOpts, opt_color, opt_width,
opt_opacity, opt_dx, opt_dy)
So the arguments to "new OffsetableMarker(...)" are a GLatLng of the
position, some {options} as specified for GMarkerOptions -- like the
icon -- and some other arguments which define the properties of the
indicator line. The only mandatory argument is the position.
var om = new OffsetableMarker(new GLatLng(51,0));
