I also find there's no mention of the option's purpose, either via tooltip, online help, man page, or on the website the online help leads to. Ubuntu does have a wiki page which explains the options, though:
https://help.ubuntu.com/community/SynapticHowto#How%20to%20keep%20your%20system%20up-to-date,%20including%20the%20Kernel
I don't see evidence of an upstream bug tracker, though. Only the development mailing list, which looks pretty dead.
