No excuse
That NOTAM has been out for ages now. More than enough time for Garuda Ops to decode it at leisure if they felt there was a need.
Furthermore, regardless of the length of the NOTAM or the level of detail in it, the crew only had to see the key lines
DECLARED DIST
RWY TORA TODA ASDA LDA
SUPPLEMENTARY TKOF DIST
and the period of validity to make them give it a good looksee.
Should be interesting to see what the ATSB come up with.
