Can you use a Thai bank account to show proof of funds for a DTV visa application without issues?

Asking for a friend so does not pertain to myself personally hence the anonymous post. Apologies if that breaks any standard protocols :-)

Regarding the proof of funds (500,000THB or equivalent on another currency): have anyone had any issues of any kind, shape or form, when they have shown the required funds being in a Thai bank account in their own (applicants) name?

My friend is worried that, since DTV is a tourist related visa, that if the funds are sitting in a Thai bank account in their own name (applicants), that the embassy processing the application might feel "but, are you truly a genuine tourist since you have a Thai bank account already?" and start asking questions.

I think it's a fair question and I have tried to help my friend Google it but impossible as it is swamped by results related to "Can I get a Thai bank account with a DTV visa?" which is not related to what I am asking here.

The group members input and first-hand experience would be highly appreciated. Thanks.
