The “logic” here is great for the humor and for an “excuse”. But, in reality, like so many things, it is built on incomplete “logic”/reasoning (by telling part of the story/situation):
A bus does stop at a bus stop but it also then again. A train also stops at a train stop but it also goes again. So while his work may stop at his work station, it should also go again.
And just as both a bus and a train get some work done (delivering people or cargo), so should that person who “stops” a work station get some work done (deliver some work).
