I think this is largely dependant on the specific topology and
redundancy in the Tier-2's network and the way they provide multiple
uplinks. When done well, with uplinks spread over separate physical
locations, well thought out IP adressing and de-centralised exits from
the Tier-2's network out to multiple Tier-n's, there's usually a benefit
to multi-homed connections to a Tier-2 rather than a Tier-1, with
minimum capacity and pricing being the most important ones.
