These trades are not happening anywhere near the after hours bid. I imagine a couple short entities agreed to trade shares back and forth and those trades are being reported. Neither of them loose and they hope to seed fear in us.
AH for all stocks you see many trades but those are not REAL trades. To give you an example I have a stock that showed on yahoo that it went up over $1, but the number was a bogus number, no trades at that that price.
