You are confusing main subject size and FOV. FOV is about the angle of the view, not the size of the subject (with varying distance..). So no, not all lenses at 1:1 have the same FOV (not even close, actually).

There is some disambiguation. If to be precise, according to Wiki, field of view is "the extent of the observable world that is seen at any given moment", so at 1:1 it doesn't differ between the lenses (like on this example from dpreview); FL only defines the distance, at which it is achieved; so angular extent, or angle of view will differ between lenses with different FL. Yes, FOV usually is expressed as angular size, but sometimes it is more convenient to express it in other metrics (like this example). IMO this difference is the key to bypass FL.
