Pause after homing X

I have Core-XY printer (H-bot) and my homing sequence is - X then Y and finally Z. Most of the times homing works as it should, but in about 20-30% of cases I am observing that print-head homes at X then stops for several seconds (could be up-to 10) and then continues homing towards Y and Z. While this is not causing any problems, I am just curios what could be the reason and whether anybody else is observing similar behavior.

Thanks
