This is the way my LX and ME Super cameras work. I recall from my days selling cameras from the 80s that the proper exposure wasn't dependent on the shutter being half depressed prior to taking the picture. Pressing the shutter button fully activates the AE as you pass the first detent, and because the systems were simple enough, AE activation was fast enough to work without pausing. Older AE cameras didn't have to do anywhere near the level of calculations that are needed to fire up modern DSLR cameras. DSLRs have more in common with booting up computers than they have with older AE film cameras.
