Why repeat moves when NOT looking for draw

I heard Daniel Rensch say during the Pro Chess League that some guy was being a good Russian school boy (or something to that effect) for repeating moves in a position that they were NOT looking to draw.  Something along the lines of how they were taught to "always repeat moves when you can".

The only explanations I can think of for doing so are:

1. to gain a little bit of increment (seems unnecessary in a lot of situations)

2. to have a little extra time to think (which doesn't yet make sense to me if the opponent moves fast)

3. lull the opponent into thinking you are going for a draw (but does that even work)

I've repeated moves because of the second reason, but it wasn't a principled thing, it just happened.  Was this really something taught in the Soviet schools of thought?  If so, why?

- gain some time

- get closer to time control

- see what the other guy's thinking

Sometimes players will actually take a worse position rather than allow a draw...

Get closer to time control!  I never even considered getting to time control because I only play quick games online or over the board with friends.  And I can now see your last two points as well.  Seems natural.

Very helpful, it just makes sense now.  Thank you.
