AC water pump suction - 2003 270 FV

While winterizing my AC, I removed the water hose from the seacock and put it into a gallon of antifreeze.  The mouth of the gallon was a couple of inches higher than the pump.  I then turned on the AC (actually heat came on because it was 57 degrees).  The pump did not have enough suction to draw antifreeze from the bottle.  Is this to be expected?

I ended up manually pumping antifreeze into the pump running almost a gallon through the system.
