I grew up in a country that adopted PAL rather than NTSC, so never saw the hue and saturation settings until my family relocated to Canada. I was baffled by how backwards NTSC was.
NTSC is only backwards if you consider it had to work with TV standards that were around since the 1920s or so. It was nicknamed "Compatible Color" because its signal format worked with existing black and white TVs just as well as color TVs. The only change was a slight slowing from 60 fields per second to 59.94 (1000/1001) to accommodate a few cycles of the color carrier.
PAL came afterwards as a full color standard from the get-go - there were other TV standards but all incompatible. TVs that could not display color dropped the color information but it was there and didn't have to be worked around.
PAL worked through delay lines on the color carrier which meant the color sync would be locked on because the color carrier would be present. NTSC didn't have this luxury and the only color sync available was the color burst signal which meant you synced a clock to it, and that clock was used to figure out the color carrier. As the clock drifts through the field (because all clocks will drift) the color will drift as well because the color information is based on the phase difference between that reference clock and the signal. But since the clock drifts, the phase does to. The tint control adjusts the phasing of the signal.
Since PAL had an AM carrier it could be synced. NTSC had the carrier suppressed.
It should be noted that other than timing and the phase alternation, the TV signal formats are basically identical - an NTSC TV will be able to view a PAL signal, but in black and white as the color carriers between NTSC and PAL are different (3.58MHz vs. 4.43MHz) so it won't be able to actually get the color signal.
In Asia, multi-system TVs were basically standard - they could receive NTSC with 3.58MHz color carrier (North America, most everywhere using NTSC), NTSC with a 4.43MHz carrier (basically Japan, sometimes noted as NTSC-J), PAL and SECAM (both using a 4.43MHz carrier). The only real difference is the electron beam timings and how to decode the color - where the carrier is, and how to sync to the carrier - using an internal oscillator (NTSC with colorburst) or an external carrier (PAL/SECAM). Other than that, the information is identical.
And yes, you can run into this if you stick a PAL VHS tape into a NTSC VCR or vice versa. You can get a recognizable picture, though the timing might be off so your TV might be unable to sync properly. (VCRs only have a single sync source - the horizontal sync and the head reads the signal from there and each line is read at output at the appropriate rate).
