1. 'load' sees no local variables from the block in which it

Indeed. 'load()' and 'loadin()' consider the loaded string as if it were a different file.
2. 'load' can be appear anywhere in the code, with no change in
its effect, as long as the function defined by it exists
by the time it is called.
3. 'function', on the other hand, can see local variables and its
effect therefore does depend on where in the code it stands.
This sounds correct.
a = 5
function foo() return a end
local a = 18
function bar() return a end
foo() --> 5
bar() --> 18
a= 2000
foo() --> 5
bar() --> 2000
_G.a = 666
foo() --> 666
