I don't see what the problem is? Synthetic oils usually do clean sludge and start leaking. Not always the case, but usually so on higher mileage engines.
They said the same thing years ago when multi grades first appeared. I remember old timers telling this when I first started. Most off the shelf synthetics these days are group 3 which is just hydrocracked earth oil, basically just a higher performance conventional.
Its the additive package not the base oil that does the cleaning (the ester based base stocks seem to clean) and these additives are also in modern conventional oil.
Its common to cleaning of the ring area and the engine to start using a little oil as this process continues but it usually subsides once the rings are free, the upside to this action is the engine sometimes gain a little compression and better performance.
