Perhaps not, C<< 2>&1 >> is perfectly acceptable.
See pod/perlpod.pod, which contains a typo.
Extract from pod/perlpod.pod below. Patch attached.

A more readable, and perhaps more "plain" way is to use an alternate
set of delimiters that doesn't require a single ">" to be escaped. With
the Pod formatters that are standard starting with perl5.5.660, doubled
angle brackets ("<<" and ">>") may be used I<if and only if there is
whitespace right after the opening delimiter and whitespace right
before the closing delimiter!> For example, the following will
do the trick:
C<< $a <=> $b >>
In fact, you can use as many repeated angle-brackets as you like so
long as you have the same number of them in the opening and closing
delimiters, and make sure that whitespace immediately follows the last
'<' of the opening delimiter, and immediately precedes the first '>'
of the closing delimiter. (The whitespace is ignored.) So the
following will also work:
C<<< $a <=> $b >>>
C<<<< $a <=> $b >>>>
And they all mean exactly the same as this:
C<$a E<lt>=E<gt> $b>
As a further example, this means that if you wanted to put these bits of
code in C<C> (code) style:
open(X, ">>thing.dat") || die $!
$foo->bar();
you could do it like so:
C<<< open(X, ">>thing.dat") || die $! >>>
C<< $foo->bar(); >>
which is presumably easier to read than the old way:
C<open(X, "E<gt>E<gt>thing.dat") || die $!>
C<$foo-E<gt>bar(); >>

Perhaps(?) that should read:
C<2E<gt>&1> redirects stderr to stdout.
podchecker -warnings -warnings could be the arbiter.
