FWIW JSC has a video splice at that point, right after Gringo's last words.
There's two consecutive 3's in JSC's telecine pattern (in GOUT terminology 71933/71934).
Doesn't prove, but suggests JSC's main source could've had subs...

Good point, the different aspect ratio and framing/cropping in the Technidisc master in the Gringo scene I demonstrated in my thread, suggests the main source for that may have had subs as well.

But I thought they specifically tracked down the "first-generation IPs" because they were subtitle-free. Does that mean that they only used said IP as a source for the Greedo scene, and not the rest of the film? (If so, that could rule out my "Technidisc/GOUT source was used to make the foreign versions" theory.)

I think it would be a good idea to try to do a visual comparison of the scene as it appears in the JSC, Technidisc and GOUT. Perhaps the "first generation" source tracked down for the Definitive Collection was not used in the Technidisc transfer (which was done in 1992 for the VHS box set). It could have even been dropped in from the JSC master.

This could mean that every pre-SE home video transfer had the scene cut in from a different source via video editing. The 80s P&S video masters dropped in the version made for cropped Academy flat prints (the kind that used to be shown on airlines; at least one has turned up on eBay before). The subtitles are optical, and the cropping is identical in the time-compressed and uncompressed versions.
