Poco's j.D groundbounce seems to activate OTG properties, the next hit makes them immediately tech (unless it's another j.D, which scores knockdown).
5D 214L, land, 5L 5H j.L j.H j.D, land, j.D (ends in knockdown)
versus
5D 214L, land, 5L 5H j.L j.H j.D, land, j.P j.K(whiffs)
EDIT:
Other shorter combos with double j.D aren't doing this, so it's probably just proration.
Also pressing K L H will do K > RC without needing another input.
Poco can also IOH with j.D. :o
j.D 214L, land, j.L j.H j.D
