Grandfathering of Tier 1 instruments w.r.t. Dividend Stoppers and Pushers

When considering the eligibility into Tier 2 for grandfathered Tier 1 instruments - lets use an example where a T1 bond (step or non-step) has a recurring call date only once every 5 years (therefore, from an original maturity perspective it should be eligible for Tier 2 capital as a 5 year bond) Does your comment re. dividend pusher/stopper language restrict the ability of such a bond (assuming it has a dividend pusher/stopper) exclude it from Tier 2 eligibility? If Yes, why are these being treated differently from regular Tier 2 instruments (which do not have dividend pushers/stoppers) that have must pay coupons i.e. an obligation to pay a coupon, which if not paid constitutes a default and thus has stronger implications than on stopping coupons on a T1 bond as mentioned above

Your response to Q 2013_31 re. grandfathering of Tier 1 instruments and their eligibility towards Tier 2 capital you note that "dividend pusher and stopper clauses that are common in instruments issued under national transposition measures of Article 57(ca) of Directive 2006/48/EC may interfere with the institution's flexibility to cancel distributions on other classes of capital instruments " - the question seeks to explore this response further
