I might be mis-reading it but the way I read it her husband is filipino too and is here on a dependent visa. Hence it definitely wouldn't normally be ok for him to claim public funds and it would effect her as the conditions of her bringing her dependents to the UK is that she can support them without claiming public funds.
As others have said previously she would be best to re-confirm this with experts or the official sources (ie the HO but don't give any names...).
