if it on the disk platters then how come if I take my two identical seagates and swap their controller boards the locked one becomes unlocked and visa versa.

I don't know what you did, but it doesn't work this way according to the manufacturers (NOT ME, I'm merely reciting what I have read on this subject...).
I've also tried that trick with disssimiliar results.
If you read the papers on this subject for BOTH Seagate and WD, both companies use the drive platters to store the lock information.
This is why it can be unlocked if those sectors are zeroed out...
This is done by some (drive specific) utilities as part of the zeroing out process.
The thought is that if you zero out the drive with the utility, there is no violation of the security.
Before the security blocks are erased, the entire drive must be zeroed in the process.
This is all documented in the information provided to OEM's by the companies.
