Quite correct, but that makes the choice sound like
a question of presentation style.
A scalar with a temporary name, as in
tempname foo
scalar `foo' = 1
will disappear at the end of the program it belongs to.
A scalar with a permanent name will persist
beyond the end of that program, unless dropped.
scalar foo = 1
Which is best depends on circumstance. On
the whole, temporary scalars are perhaps better,
as they impose less load on memory (usually trivial
in practice) and keep things defined only in a
relevant namespace (often important in principle
and practice).
