Yes, but using a membrane isn't the one defining feature of "mechanical" vs. "non-mechanical". There are RD keyboards that use a PCB, but that doesn't make them mechanical.

He totally did! At 4:48, he says: "Actually, some Model Ms do use rubber domes, but more on that later." Then, at 6:01, he states the following: "In 1990, IBM sold part of its keyboard manufacturing division to what would become LexMark. Lexmark continued to make these keyboards for IBM, but more cheaper [sic]. This Model M, from 1995, demonstrates some of the changes, including one good one: drainage holes, to protect it from its arch-nemesis, water! Along with several... less good [sic] ones, like a lighter backplate and plastic shell, a fixed, instead of removable, cable, a monochrome legend on the keycaps aaand... rubberdome switches. To be clear there, good rubber domes, but still.".
So, yeah, he totally said that Lexmark-made Model M keyboards contained rubber domes instead of buckling springs.
