You are reading it right, Diki, as that's what the chart shows, however, that 3rd line appears to be incorrect.

From Yamaha sites:

"Articulation Element Modeling (AEM) is the technology for simulating this characteristic of instruments. During performance, the most appropriate sound samples are selected in sequence in real time, from huge quantities of sampled data. They are smoothly joined and sounded - as would naturally occur on an actual acoustic instrument.

AWM is Yamaha's original system for effectively using sampled waveforms in synthesizers and tone generators. The strength of AWM synthesis lies not only in its extraordinary ability to "shape" and control the sound of the samples with a comprehensive system of envelope generators, filters, key scaling parameters, modulation, and more. AWM voices can have from 1 to 4 AWM elements. Each AWM element can use a preset wave or a sampled waveform. The ability to combine AWM elements means that you can, for example, combine separate samples for the attack and sustain portions of an instrument's sound, with independent control over each."

FSX is the designation given to a type of semi-weighted keyboard action used on Tyros2/3/4 and Motif XF/XS.

All the above arranger models use AWM as a sound source.
