ST_Crosses will use an index if available. 

1. ST_Crosses(
	rast1 raster, nband1 integer,
	rast2 raster, nband2 integer
) -> boolean

2. ST_Crosses(
	rast1 raster,
	rast2 raster
) -> boolean

After digging at the purpose of ST_Crosses, this function would always return false for two rasters, which are in essence two areas.
