When you have done it once, it does become familiar like the Send button. This is a more natural approach because we know to a certain extent how the App functions.
Though it is predictable that when we pull out funds from CS, they are being Sent somewhere, then the SEND button is understandable. The SEND button on the main page is more like descriptive, whereas, at the end of a transaction it's more like the 'execution of'. I can understand where one can be confused.
May I propose, if the Send button is not linked to other Send buttons in the App, it could be followed by 3 dots EX: SEND..., or just have a different background color. When a buttons leads to another page in the App, it can have the blue background(BG), and when it terminates a process another BG color.
We know people get uneasy when terms can be misleading, specially when playing with a form of value, in this case BTC. Personally, I think SEND is the right button to go there.
