It means that Mach 1.6 is not in the practical envelope for the F-35B, so that its tactically useful maximum is somewhere between 1.2 and 1.4. How different this is from a Marine F/A-18C (heavier than an A but with the same -400 engine and frequently seen with a Sniper on centerline), I cannot tell you.
Also, the most sensitive instruments known to science could not detect, let alone measure, my level of interest in what the repulsive crew of Walts, toadies, sciolists, sociopaths, frauds, pseuds, dimwits, basement-dwelling pizzavores and rhymes-with-bankers at some other board thinks about this subject, or indeed anything else.
