This is also common in Dvorak, for example. Strauss-Berlioz describe a 
precise rule for this (according to them, violin clef for cello is 
written one octave higher if it occurs i) right at the start of a piece 
or ii) after music in bass clef; it's written _loco_ if it comes after a 
passage in tenor clef). But then they (i.e. probably Berlioz) continue:

"Dieser durch nichts zu rechtfertigende Gebrauch führt um so häufiger zu 
Mißverständnissen, als manche Violoncellisten keine Notiz davon nehmen 
und den G-Schlüssel stets nur in seiner wirklichen Bedeutung nehmen."

(Roughly: There's no justification for this usage which often leads to 
confusion, in particular since some cellists are unaware of it and 
always read the treble clef in its standard meaning.)

... and what's even worse, as soon as one has gotten used to this rule, 
one stumbles across (recent) scores that don't adhere to it any more.
