The same happens to older SECAM decoders (with frame identification only) when you force colour on a SECAM signal without frame ident signals.
When you switch them on or change channel, every other time they start with wrong colours (interversion of R-Y and B-Y).
It is generally sufficient to change channel once or twice to catch the right colours.

Regarding the SONY "non PAL" decoder with its two Xtals, I wonder if its cost was really much lower than a "true" D-PAL decoder paying the PAL license.
