You are right, zone 1 is technically not called a fat burning zone but apparently this is the zone that uses the fat stored in the body as fuel for cycling according to Chris Carmichael (p10. The Complete Book of Long Distance Cycling, by Edmund R. Burke, PhD and Ed Pavelka).
It's true that lower intensity work favours fat metabolism (as opposed to using solely fat) which in turn correlates with the use of aerobic rather than anaerobic pathways - so good for establishing a solid base.
However, the zones are not discrete boundaries no more than rep ranges in weight training are discrete. You get a mix of adaptations usually although one on is generally more favoured.
Personally I think HR training does have use but I have been referred to training using power output as being a more reliable method of guaging work and from what I have read so far that does seem to be correct (I am fairly new to cycling but not exercise phsyiology.)
I think if you use HR training as a recreational cyclist you will see many positive results but if you want to ramp up results then you would drill down on measuring power output.
