I'm not sure what General Absolution has to do with any of this. 
It works on the same principle as BOD properly taught is my understanding.
Rare as is BOD these days but effective when properly given. Meaning both the recipient is in need because death is imminent - both are in need of the Sacrament because of either mortal sin or original sin - both MUST BE GRACED WITH PERFECT LOVE - BOTH UNDERSTANDS THAT the SACRAMENT is required at a later time if death did not occur.
Can. 960 Individual and integral confession and absolution constitute the sole ordinary means by which a member of the faithful who is conscious of grave sin is reconciled with God and with the Church. Physical or moral impossibility alone excuses from such confession, in which case reconciliation may be attained by other means also.Can. 961 ง1 General absolution, without prior individual confession, cannot be given to a number of penitents together, unless:1ฐ danger of death threatens and there is not time for the priest or priests to hear the confessions of the individual penitents;2ฐ there exists a grave necessity, that is, given the number of penitents, there are not enough confessors available properly to hear the individual confessions within an appropriate time, so that without fault of their own the penitents are deprived of the sacramental grace or of holy communion for a lengthy period of time.
