This person was me and the statement was not made based on their last 'abnormal' performance.
Everything goes 'normal' we have 6 teams ranked above them at least:
CHN#1#2, RUS#1#2#3, CAN#1
Amongst the other teams for Top10 we have:
ITA#1, AUT, USA#1#2, PRK, CAN#2
So (potentially of course), including H/S we have 7 teams competing for 4 spots.
I have no doubts that H/S could manage Top10 on 2 good days. But they have no big PCS advantage to the other teams, so it comes down to TES on the days.
With H/K (almost the same level) we would have 8 teams for potential 6 spots, 2 of them germans.
So 2 teams entered seems a pretty good start to hold on to those 2 spots (especially with 13/14 placement still is enough for 2 spots).
1 team entered seems a lot like a 50/50, 60/40 chance to me, especially as H/S are not known for holding it in the FS together on regular basis.
