I'm not sure if you mean athletes running 53 should be capable of 1:56-58, or a 53 is an equivalent performance to 1:56-58, but it's not true either way.
In the case of the former, 53 flat is around the requisite speed for a true aerobic machine to run sub-1:58, but the vast majority of sub-1:58 athletes--and almost all 1:56 athletes--are going to need to be at least a second quicker. The guys running 1:56 off 53s quarters are far and away the exception rather than the norm.
In the case of the latter, 1:58.00 is worth roughly 50.5 for a quarter. 1:56.00 is worth sub 50 easily. For reference, Mercier and IAAF tables have 1:56 worth about 49.7.
Maybe they are equally competitive times in their respective fields, or equivalent for those who are primarily sprint oriented, but distance guys (800/miler types) with 50-53 400 speed are not slowing down by 8-9 seconds per lap to go from 400 to 800. If these tables are based on what times would be equally competitive against the people in each event, then they are probably skewed because of 200/400 guys, who are fast, but don't compete at 800.
