If I understand you right, when the liver decides to dump it will dump all it's store into the system, this is because a hormone (glucogen) same as the hypo kit, tells it to... But saying this because it takes a long time for the pancreas beta cells to send the the hormone to the liver to dump it's store. the slowness of this responce is due to the diabetes faffing up the circuit..
How long it take this process to happen can be quite a long time, and of cause any active insulin you have in your body will continual to lower your BG,
The lower and longer you are hypo the more awful you feel when your BG returns to normal, and the longer the recovery time is..
This is a kind of back-up system we have, but can't be relied on to do back up though, as your store can be effected by a previous hypo/s so not enough there, and also drugs like alcohol prevents the store being maintained, then theres the possiblity that you may not have the necessary bit to create the response..
Hopefully I haven't confused you too much
