Since the orbits' Mean Motion differ by less than 0.02, they will drift
apart by less than 2 min/day, and meet again in little over 50 days.
Hera are the most recent elsets from OIG:

I obtained the latest 5 elsets for 26384-26387 and ran Rob Matson's
AllCola on them. It showed the minimum separation 11.2 km (mainly
vertical) at 8/24/2000 1:12:58.44
26387 should overtake all three objects within two months, but AllCola
didn't converge. 26386 has a negative drag, so its predictions are
unreliable. Here are the ones I/it found :
26384 26385 26386 26387
26384 - Oct.25 Aug.24
26385 - Nov.27
26386 - Sep.04
26387 Oct.22 -
