There still seems to be some problems with refreshing buffer contents. In the example below the buffer gets refreshed before the first popup menu, but not before the second popup menu.
Redisplayed is blocked while popup menus are active. The user's attention is on the popup menu, so I don't see it as a problem, and AFAIK there were good technical reasons why it is as it is, to do with GC and the arbitrary data structures that might be associated with the menu.

But is that really what blocks it here? I try to use (sit-for 0) between the popup-menus but no redisplay happens there.

In the case where I am using this the buffer should be updated between the popup-menus. I think the user expect that to happen.

Why should redisplay be blocked between the popup-menus? Are the popup-menus active when the function choosen is called?

I consider this bug and I can see other bugs here that seems related. Though I do not know if these bugs are only related to the w32 port.
