The Two "Mottos" of the Golden Company (Spoilers Extended)

The Golden Company is known to have a boast/motto and a battle cry:

Our Word is Good as Gold

"Sellswords break their contracts all the time."

"Not the Golden Company. Our word is good as gold has been their boast since the days of Bittersteel. Myr is on the point of war with Lys and Tyrosh. Why break a contract that offered them the prospect of good wages and good plunder?" -AFFC, The Soiled Knight

Beneath the gold, the bitter steel

"Beneath the gold, the bitter steel" became their battle cry, renowned across Essos**.** -TWOIAF, The Targaryen Kings: Daeron II

and I just noticed that they make sense together when you think about it. The Golden Company's word is "good as gold", but beneath that gold is "bitter steel". This alludes to the fact that although they "never break a contract", the only time they will is for Bittersteel/bitter steel which is basically:

• Bittersteel's skull is dipped in gold and carried before the Company (as are all captains of the GC)

Ser Aegor Rivers had famously commanded his men to boil the flesh from his skull, dip it in gold, and carry it before them when they crossed the sea to retake Westeros. His successors had followed his example. -ADWD, The Lost Lord

• You can also look at it like "beneath that shining repuptation/gold is a bitter desire to return home:

They were exiles and sons of exiles, dispossessed and unforgiven … yet formidable fighters still. -ADWD, Tyrion II

TLDR: Maybe not intentional, but I think it is cool how the motto and war cry of the Golden Company make sense when combined. They won't ever break a contract, except for home.
