I got the impression "copies" was referencing their artificial status and reincarnating. The term was used in Evils Kingdom too; it was Gammon's conclusion to seeing how the Servants reacted to Lemy's death:

ハンゼル&グレーテルを元にしたコピーでしかない.

Based on both contexts, it sounds like they're degrading with each reincarnation, which I guess affects their willpower if they are unable to remain independent of Banica/MotG's will.

The phrase is literally "shadow of one", so it could be "one's shadow", "a shadow", etc. The iillustration has their shadow make an odd wavy form when they are running so that might be it.

When they are resting in the previous illustration, you see blackness almost in pools around, one under Gretel's seat (where her shadow shouldn't reach), and a few on either sides of them going off-screen. It seems like the shadows are coming from them or possibly the glass bottle somehow.

I hope OSS Act 3 and the Sloth books clarify this. XD
