Quin etiam, quod necessariam rem coactus

[ClassicalSoul]

I can't help but read this quod as concessive. But I'm almost sure that's not the case. What's the role of the bolded quod?

Quin etiam, quod necessariam rem coactus Caesari enuntiarit, intellegere sese quanto id cum periculo fecerit, et ob eam causam quam diu potuerit tacuisse.

 

[Pacifica]

"as for the fact that"
