That's probably because snort isn't using a libpcap filter of that sort;
libpcap (the code to parse and generate code for capture filters is in
libpcap) doesn't support generating filters for the PPP part of PPPoE,
because nobody's written code to make it do so.

Perhaps someday somebody will write that code.  I don't have time to do
so in the near to medium-term future.
