Yes the aliquot strings are supposed to be tuned an octave higher.

The odd one or two that I've come across, it all seemed a waste of time to
me. Maybe when the pianos were brand new, it did something to the power
and sustain of the treble, have it an extra 'sparkle' or something!  But
it just seems to me like an awful lot of extra work in tuningt, for no
gain tonally.

There was some talk a year or two ago about oxidised leads. I think there
was a suggestion about applying something to seal them after cleaning,
varnish or something, to prevent further oxidation.

Best regards,

"After arriving in Dallas in 2004,
cust. had me out to tune & all things were well. Last week several keys were
catching on each other. Upon inspection it appears/best guess is that after
climate change/re-location keys were drying out & shrinking causing leads to
back out & corrode. I lightly removed approx. 80 key leads removing
lead/corrosion. 4-5 had begun to split & I suggested I inspect during next
tng. I suggested that after 5 yrs. keys may not shrink anymore. Can anyone
give a discourse on the Aliquott grands. Tuning etc. No articles found.
After calling a few local heavyweights, consensus is tune the sympathetic
string 1 octave higher that unison. I'd love to hear a little bit on the
thinking/creative design behind this. These sympathetic strings sounded
pretty dead, no resonance".
