By 2001 I'd been away from VHS for 3 years so I don't know if they changed anything.
The machines I was referring to were from the late 80's and through to around 1998.
By that time many manufacturers were starting to end production of VHS and Panasonic were one of the first to badge machines they didn't make.
AIUI by that time most of the VCR's on the market were made by only one or two companies
After I got into dvd in 1998 I gave up completely on new VCR's although I retained an SVHS one . Still have 2 Pannys in the garage
Index systems certainly didn't match in the early days when each manufacturer was introducing its own - which was a constant source of irritation.
Your findings would suggest they standardised them during the latter years of VHS
