Medium frequency Python developer at 500k GBP

Does this Python developer job really pay 500K GBP? These type of job descriptions throw me off  the bottom:

. Total compensation is estimated as being up to £500,000 but this is purely performance relate linkedin.com/jobs/view/3492926509/?eBP=JYMBII_JOBS_HOME_ORGANIC

There was also a mention of base pay being 100 -200 GBP. Uh that is now 500 GBP
