well ....no ....
counterbalancing 'weighbeams' automatically move weights for balance - loads are according to 'distance moved' count
your link is a good find ... showing afaik ....
balances with full decoupling linkages- but using 6 (inert) single-component-of-load cells instead of 6 (live) 'weighbeams'
the decoupling linkages were IP from government labs c.100 years ago
this design approach is conservative, complicated and expensive (and bulky) - but offers some user benefits
decoupling can be done numerically and/or by design of the load sensing elements (also benefitting stiffness ?)
f1technical.net quotes Aerotech's disclaimer ie that some amount of compliance is unavoidable
'naturally sprung' suspension could be ok with intelligent (eg electromechanical) spring platforms and without full decoupling
