probably did, although actually the example is completely wrong:-)

comparsion of a node set to a number is one place where number() _is_
implictly applied so
@foo=1
is exactly the same as
number(@foo)=1

A better example would be comparing two attributes

@foo = ../@foo

would be false if
this node had foo="1" and its parent had foo="1.0"
as the default is string comparison but 

number(@foo) = number(../@foo)

or even just one side, eg:

number(@foo) = ../@foo

would force numeric comparison so then 1.0 and 1 would be equal.
