FLR (M) Combining Category F with Category A/B

[salvatoresays]

I will be applying for my wife's visa after 4 months
As per my SA302 for the last financial year:
Income from employment : 7000
Income from Self employment 13000
total : £20000

Appendix FM 1.7: Financial Requirement
9.3.6
'Income under Category F or Category G can be combined with income from salaried
and non-salaried employment, non-employment income and pension income in order to
meet the financial requirement. However, unlike with other Categories, these sources of
income must fall within the relevant financial year(s) in order to be included. Under
Category F or Category G, all sources of income must fall within the financial year(s)
relied on and must still be a source of income at the time of application]. For example, to
count income from property rental the income must have been received during the
relevant financial year(s) and the property must still be owned by the relevant person at
the date of application'

Pointing out: all sources of income must fall within the financial year(s)
relied on and must still be a source of income at the time of application

Can someone please explain the same source of income at the time of application considering I have moved to a different job in the new financial year,
Does same source of income means employment or the same Job?

Thanks
