This ensures that, when pressed in, the piston cannot go in all the way.

–

Info
This position is necessary for installation.
If the timing chain tensioner is now pressed again and is only extended a
maximum of half way (it is prevented from extending completely), this locks
the detent mechanism and the timing chain tensioner can no longer be
squeezed together. This function is necessary in order to ensure sufficient
timing chain tension even at low oil pressures.
