Here's a slightly different (banana-themed) workaround. Run the following before making the plot:

```
# monkeypatch legend duplication of trac #11225
def fix_piecewise(fn):
import types
def fixed_plot(self, *args, **kwargs):
from sage.plot.all import plot
return sum([plot(f, a, b, *args, **(dict((k,v) for k,v in kwargs.items() if i == 0 or k != 'legend_label')))
for i, ((a,b),f) in enumerate(self.list())])
def fn2(*args, **kwargs):
ans = fn(*args, **kwargs)
ans.plot = types.MethodType(fixed_plot, ans)
return ans
return fn2
Piecewise = fix_piecewise(Piecewise)
```

after which it should behave.
