Due to Mathematics and the progression of number in the current numerical numbering system, 6'1" is greater than 6'0" so if that rule is true and is constant then by default 6'1" plus is also greater than 6'0". With that being true the previous statement is correct.
I may have needed to dumb it down for you a bit so you would understand.
(The boy stands a good 6 foot or better)
Can you understand that a little better. I can also break it down for you a little more by saying:
(He's a tall feller)
Clear NOW?

You may need to dumb that down for yourself. It is redundant to say he is both 6'0"plus and 6'1" plus. If he is 6'1" plus why put the 6'0" in there. Looks like you just like speaking in hyperbole. That is so unlike an am.
