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.
As I said, in the case of the former (what a 53s quartermiler should be able to run in the 800) 1:56 is way too fast. That's holding ~92% of the athlete's 400 PR for two laps, which is slightly better than what the best 8/15 guys in the world do. 1:58 is plausible off 53.00 quarter speed, but I'd only expect it from 8/15 athletes with a bent towards the 15--never from a 4/8 guy.
I'm not really sure what you mean by the tables being skewed; the second case (which I think you were referring to with the "slowing down 8 seconds per lap?) is just stating that 50.5 in the quarter is an equivalent performance to 1:58 in the half. Not that a 50.5 quartermiler could run a 1:58 half or a 1:58 half miler could run a 50.5 quarter.
