Is it me or is this wrong? In the masculine section of this table, isn't it supposed to say он instead of я?
Maybe there's explanation somewhere to this table, but I think they just didn't bother to list all the pronouns because there're only so many verb forms in the Past Tense anyway.
- The listed masculine forms are true for all я, ты, он
- The listed feminine forms are true for all я, ты, она
- The listed plural forms are true for all мы, вы, они
- And only neuter singular stands apart
So all in all 4 verb forms of each verb aspect.
The main determinants here are not the actual pronouns but the gender and number masculine, feminine, neuter and plural (exactly 4 for each verb aspect), the listed pronouns are mentioned just as an example of each determinant because in themselves they're irrelevant for determining Past Tense verb forms.
If all the listed pronouns are deleted the table will remain correct and exhaustive for the given verb.
