Is it allowed for the photographer to sign with the account name in model release?

Hello contributors, 

I would like to check if it is allowed for the photographer ' stock contributor account owner' to sign the model release document with the account name instead of his legal name.

I mean, my name in contributor account is 'Worker', that is certainly not my real name. according to this information 

From an adobe document "The photographer's first and last name on the model release must match exactly with the first and last name on your contributor account." I should use that name in my account to sign the document. BUT, shouldn't the model release document be a legal document so you should use your actual name?

I would like to know if it's allowed to use my account name or not.
