Salazar 5K/10k training

I remember him saying that he did a lot more stuff like 10X600 and 8X700 since moving to 5000. The only thing I wonder about is the timing. Lagat takes 5 weeks couch potato off, and week 1 ended on 9/28 according to his twitter. Now, if you’re the coach and you had a guy taking 5 weeks off and ending that at the end of October, would you really be going to 10X600 in November (unless they start as tempo)?
