Crossed batons or arms means STOP!
Supposed to be both arms or batons held crossed in front of and above the head, but I often see in the USA, marshallers will hold both their crossed batons above their head in one hand, (while they are waiting for the tug to get clear or whatever).
My guess would be that this guy was getting tired arms and so was holding his crossed batons much too low. File an ASR - not to get them into trouble, but because it is important that signals to aircraft are correct and unambiguous.
If you can see crossed arms/batons directed towards you, then STOP ! There might be something going on that you cannot see !
