I think it's a big fat clue, whatson - and one that an English teacher might even DIS-agree with. To be highly effective, web writing needs a lot more redundancy than offline writing. Yes, the fact that snippets are extracted and taken out-of-context is part of it.
Also, visitors often scan a lot and then jump into reading a sentence. If the meaning requires them to back up, you may have just turned that visit into a "short click".
