He walked that back by saying he meant what they wrote for those scenes was apparently too taxing for the VFX team to make real that they cut them before ever sending them over.
He’s probably referring to the extended Luke and Leia flashback scene.
My preferred saga experience:
TPM/AOTC/ROTS (Hal 9000), ANH/ESB/ROTJ (Despecialized), The Mandalorian,
TFA (Starlight), TLJ (Fallen Knight), TROS (Resurgence).
May the midichlorians be with you.
