Does PPC 2.0.2 handle alignment of data the same way as former

The statements below have nothing to do with alignment.
The type of pBoxtemplate is ^word.
Is it not true that
(dword(pBoxtemplate) and 1)=1
evaluates to TRUE, if and only if pBoxtemplate is NOT aligned to a
word boundary (16 bit boundary)?
And then, assuming pBoxtemplate is aligned to word boundary, is it
not true, that
if (dword(pBoxtemplate) and 2)=2
evaluates to TRUE, if pBoxtemplate is NOT aligned to a dword
boundary (32 bit boudary), causing the statement
if (dword(pBoxtemplate) and 2)=2 then inc(pBoxtemplate);
to make the pBoxtemplate align to a dword boundary (by eventually
adding 2 to pBoxtemplate (because sizeof(word)=2)??
Yes, but this is independent of how the compiler handles alignment of
data.
