Yes. At least that was my conclusion last time we bumped into such
a bug. I even added a comment in buffer.h about it:
/* !!!FIXME: all the BUF_BEGV/BUF_ZV/BUF_PT macros are flawed:
on indirect (or base) buffers, that value is only correct if that buffer
is the current_buffer, or if the buffer's text hasn't been modified (via
an indirect buffer) since it was last current. */
