Which means he had to swim up to a depth of 30 ft , for shallow drift dives
this is doable , for  deep it is too risky, if he is deeper than 30ft the
reel will go by him too fast and if he try to grab it he goes up also , a
bad day.

I do not understand this , it does not make since , to attache his hose to
the bag as soon as he added air they both will start to go up , one small
mistake and another bad day. Again too risky.

It does not sound safe to me.

This would require the removal of the second stage from the mouth , which
will cause an initial lose of gas , if you are sending up a bag in a life
depending act because of low gas then you are fucked , if you are sending
up a bag as part of your dive plan , then sooner or later your fucked . To
send up a bag with hanging reels , loose line to get tangled in a wreck or
yourself your fucked.A lift bag should be used only when needed , some
wreckers carry 2-3 , one is always saved as a back up if needed to save
your ass , the others are for artifacts.
A lift bag should  not be part of your dive plan.It should be practiced ,
one should be able to deploy it in under a min. , even while having great
mental stress .I like to use the open bottom bags , I can fill it without
removing my second stage from my mouth and no lost gas, I only need to tilt
my head and open the bag just over my exhaust port and the used gas will
fill the bag ,  this causes no stress or lost gas.Lift bags can save you or
kill you , its just that simple.
