EEPROM 10,000,000 for bs1 & bs2, but only 100,000 for bs2p, bs2pe and bs2px

According to the·website FAQ the bs1 and bs2 eeprom is rated for 10 million writes,
but the bs2p, bs2pe and bs2px are only good for 100,000 writes. That's a 100x difference.
How can it be so different? Is this a typo?
Also the data sheet for the eeprom chip (24FC128)·shows·that·it can do·more than·1 million writes.

Does the BASIC Stamp module lose its program when I remove the battery or power supply?
No, your PBASIC code is stored inside a serial EEPROM on-board the BASIC Stamp module. EEPROMs provide non-volatile storage; they retain memory even without power. The EEPROM used in the BASIC Stamp 1 and 2 modules are guaranteed to function properly for 40 years and for 10,000,000 write cycles per memory location. The EEPROM used in the BASIC Stamp 2e, 2sx, 2p, 2pe and 2px modules are guaranteed for 100,000 write cycles per memory location.
