The whole Platonist position begins from a definition of "exists" that works equally well for abstract and concrete objects.

I'm yet to see such a definition. Do you mean the "definition" (a postulate, really) such as the one on Wikipedia? (SEP isn't any better.)

With a lower case "p", "platonism' refers to the philosophy that affirms the existence of abstract objects, which are asserted to "exist" in a "third realm distinct both from the sensible external world and from the internal world of consciousness..."

If so, then it's a separate definition, not something that "works equally well". Besides, I have trouble understanding why one needs to differentiate between the abstract world and "the world of consciousness".

It's just a way of categorising Platoniists. Conceptualists think 3 is just a concept in their mind, Ptatonists don't.
