Spaghetti code is when procedural/functional coding goes wrong which is pretty much opposite of too much abstaction. Basically, spaghetti is what was before OOP when it went bad. At least, I did not heard people to refer to too much abstraction as spaghetti before.

For the record, this one is not that bad. It is comprehensible and pretty easy to refactor. Real spaghetti is something you have no idea what it does.
