Anyone have a suggestion why these behaviors would be different?

To claim HP disable financial register stack-lift on purpose is a bit weak.
This could explain away almost anything, even above odd behavior
(real use cases suggest ... it is documented ... uh, it is a feature)

Sadly, by claiming bug as feature, it will never get fixed.

My first time beaten by this type of "feature" is with RCL (Yes, it is also documented)
Say, 5 is stored in memory 0, with a clear stack:

5 * 5: RCL 0 Enter x => 25 -- so far so good
5 * 4: RCL 0 Enter 1 - x => 100 -- ???

Uh... no.

Although there are indeed bugs in every calculator (HP included) this is clearly not the case here; Thomas and Dieter's detailed comments explain similar cases as well.

Bottom line is both RPN and RPL require extensive use to really grasp. The subtle reason this was changed here (after storing the 12C Financial Values/Registers) is almost certainly as explained in my post above; since it does not occur upon storing normal registers (as is the case on all other machines), it's clear this was deliberately changed for the financial registers.
