IRT kuroiwaj, I see no contradiction between the two paragraphs.  The first paragraph points out that the professionals that Trump has hired are bound by a code of ethics to be confidential with Trump's tax information.  Because they are hired by Trump they will present Trump in the best light possible.  Confidentiality also means you cannot reveal questionable dealings or transaction (squeal) to the authorities unless of course your client wants you to.  So in other words these professional have a conflict of interest because they are being paid to represent Trump.  So their assurances are kind of meaningless.  Got it?

The second paragraph is pretty self explanatory.  Trump promised to release his returns and he says there is nothing wrong with them.  If so then why not release them?
