Usage of 'limit' keyword when filling with a value

From SO: http://stackoverflow.com/questions/29906512/pandas-variation-on-filling-nan-whats-an-elegant-and-pythonic-way-to-do-thi/29906743?noredirect=1#29906743

When doing df.fillna(10, limit=2) what is limit=2 doing?

The docstring says:

limit : int, default None
Maximum size gap to forward or backward fill

But this only explains for filling with a method, not for filling with a value.

Comment of @jreback at SO: doc string wrong - limit is how many to fill
