I agree too. My theory is that sometimes the tin leaches out of the solder, 
affecting its melting temperature - especially if the original joint was 
done in a solder bath, and it hasn't been kept properly topped up. It 
operates at a temperature that still does a good joint, but when you come to 
rework it then you notice it doesn't flow well because your iron has lower 
thermal mass than the solder bath.

Adding new solder adjusts the tin/lead balance and adds some flux as well to 
help it flow.
