To make it simple we must separate between synchronization and the need of full mesh iBGP, as they are 2 separate issues.
iBGP rules state that, a BGP router won't advertise routes received from an iBGP peer to another iBGP peer, and thus you'll need to full mesh your iBGP peers or use Route Reflectors or even play with Confederations.
But for the synchronization, a BGP router with synchronization enabled will not advertise iBGP-learned routes to other eBGP peers if it is not able to validate those routes in its IGP (thus you'll have to redistribute BGP into IGP to have it working).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
