Somewhat OT: once flying HGK-MUC-HEL German customs were out in force and stopped most transit pax - so much so, that they wanted to see receipt for my wife's watch (either they were looking for counterfeits or for high value, undeclared items) So customs was done at first point of entry.
To be clear, it is entirely possible that someone arriving initially from outside Schengen (ie no green stripes on luggage tag) is stopped by customs when exiting through the green lane, as part of a random or indeed targeted check. I see this all the time.
