We aren't privy to NS methods. Had East passed then 2♠ might well be Pass/Correct. After East's double, South's suit-bids are more likely to be natural. Presumably, redouble would ask for North's 2nd suit. 2N has more than one likely meaning. Anyway, IMO, with ♥ tolerance, South would be likely to pass, in tempo.

So, we don’t know enough about the methods of NS to give a reasonable opinion.
OT: I’m glad that N is not my partner. An overcall should show values in the suit and also be lead directing, at least that’s what I’ve been taught. At this vulnerability it’s begging for problems.

"demonstrably suggested over…"

It's not enough to say some call is "demonstrably suggested". Demonstrably suggested over what? More importantly, when we're asking whether some call is demonstrably suggested over some other call, "some other call" has to be a logical alternative, and "some call" has to be the call actually made by the player who had UI.
