Dropping 3rd FPP to get something else?

[Beth33]

@AuntB_luvsDisney and @Nicky_S, I just saw something Len said in an older post about FP+ that confuses me a little.

@Lentesta

In some cases, [the TP optimizer] may tell you that 1 or 2 advance FPs are more useful than 3, because it allows you to get more day-of FPs faster. So rather than getting a 3rd advance FP for, you know, Imagination at 8 pm, it may just suggest 2 advance FPs so you can get a second, day-of Soarin’ FP at noon. (Assuming you want to ride Soarin’ twice.)

This seems to imply that if you only book 1 or 2 FP+ in advance, once you use those up you can get another FP+ in Tier 1 in the same park. Do you know if this is the case, or if Len was mistaken? Or maybe things have changed since 2014 when he wrote that?
